No rental depot has good reviews. Most folks forget to write anything when nothing goes wrong.

Easy but not a short walk. I worked in that area a few summers ago and walked from South Station to about half way to the cruise ship dock daily. And sweated like crazy doing so. Lots of construction, as @latebloomer56 mentioned, but it's fairly well signed and lots of crosswalks with walk signals

Þingvellir is great but it's mostly a natural site. It is, of course, historic, but I don't recall seeing anything physical there from Viking times Most of the other items I have seen, they are cool, but they are replicas. As long as you are OK with that you should have a great time. We drove past Snorrastofa on our way to a lava tube near Hotel Husafell , it struck us as being "another museum" (we aren't museum people when it comes to Iceland) that we didn't check out.

Not sure how many real Viking sites you will see as the snow and ice and volcanos and earthquakes in both locations tend to make it pretty hard for their artifacts to remain untouched. In over a month (so far) in Iceland I have yet to see a Viking site. To be fair, I haven't looked for any but I've had 5 amazing trips seeing about 2/3 of the country so far, and if there had been a Viking site along the way I'm sure I'd have been told about it by a guide or read a sign about it.

Easy to take public transport or a cab or uber to the HOHO stop

It's a 10 minute walk per Google Maps. You can "walk it" with Street View to see if there are any obstacles that might make it more difficult for you

The water taxis have offered this for a few years, it is not cheap, but it is well regarded. An alternative is to leave your bags at a convenient hotel for a tip, but then you're responsible for your own transportation

Get in the cab first before you tell them your destination. Be ready to take a photo of their license on the back of the seat if they refuse to take you.

Apartment rentals in NYC are generally illegal no matter the platform. You are much more likely to be scammed than you are to find a safe, LEGAL and convenient private rental in the city

Talking to any driver who walks up to you at any tourist site is a mistake. You'll never get a good deal that way and it may not be safe. Go to the cab line. Get in. Tell them your destination. They can't refuse. If they start to refuse, take a picture of their license on the back of the seat and they will take you to your destination. They get lots of train station rides from the ports.

As #3 said, Iceland is best done by land. Easy to drive, not many roads, very well signed, almost everyone speaks English. Seeing a glacier or a waterfall with no one but your family is incredible. You can't get that on a cruise where you are either going to be on a bus with 40 other folks or even on a private tour with a guide.

Good point. Hard to tell from @imalori 's post which airport was meant

Lots of glaciers in Iceland (still part of Europe) to see. Easiest from land. Some are receding, others are actually growing but those are rare. The point wasn't about luxury vs. global warming, though, and I think you know what I meant.

Tip rate is usually 20% or so. More if the driver helps with alot of luggage. A bit less if they drive wrecklessly or are rude or have the radio loud.

Downtown Reykjavik is where the cruise port is. The airport is a solid 45 minute drive away. Blue Car Rental is the preferred provider based on reports I read regularly on TripAdvisor, and we used them last time we were in Iceland. When renting a car in Iceland consider insurance options CAREFULLY as roads can be a little rough and winds can be strong, and windshields can get damaged by gravel from roads and strong winds can literally sandblast the paint off of a car .

Yes, yes, yes, and I don't understand the last question. My poles wouldn't stay locked open so they offered to replace them but we only needed them one day so I asked for and got my rental fee back on them

If you replace "Antarctica" with "Europe" does the rest of your statement change? The price differential was small so the choice for us to go luxury was easy.

You won't have any trouble taking a cab, uber, or public transit to catch your flight

We find Google Maps or Citymapper do an excellent job of helping us figure out the NYC subway routes

It's free, it takes about 90 minutes total, but it is a distance view

That Fairfield is in an industrial neighborhood near a train yard. The Element is in a much nicer area. It is closer to a grocery store and to the T, but that's about the only advantages I can see

For us we took a luxury trip to Antarctica because it was 25% more than Hurtigruden and similar options and we felt the comfort and better food options, etc, were well worth it. There were no "cheap" possibilities when we sailed in early 2018

Make sure the pedicab price is fully agreed upon BEFORE you get on. They regularly charge $5-$6-$7/minute and upwards from there. Uber apps work fine. Arro for cabs or hail the old fashioned way. Traffic can be a real issue with cabs and ubers. We've taken the NYC subway hundreds of times, as we visited 5-6 times/year for 25+ years and never had an issue. Definitely the fastest way to get around

There is a Dunky very nearby. MyDiner is our favorite but locals know it's not the same since the move. Is Scola's still there? Galley Diner is also not far away and is quite Old School

We enjoyed the Conway Scenic, although we took it in summer, so no color. We REALLY liked the Mount Washington Cog Railway. Dress for COLD temps if you chose that one!
