I'm sure they have done their research and are deploying the ships in the manner that makes the most economic sense. The captive audience also has the ability to drive to FL if they choose.
A lot depends on the rules of the port country, Italy in this case. There was a time this was allowed if requested and a small fee paid. Unsure if it is still allowed by Celebrity, but the country rules trump all.
Since most of my cruising takes place during our winter months, the probability of weather delays dictates at least a day early. Direct flights are risky enough, but ending up with a connection in Denver, Minneapolis or Toronto can easily spell disaster.
I also am not happy with the timing of the notice. The overnight was the main reason for choosing to extend my Panama sailing to Vancouver. The way the email reads is that it is an issue for the Pacific Northwest and cruising speeds need to be restricted. The modified itinerary extends the cruising time from SF to Victoria (PNW area) by a whopping 15 minutes. That will sure make for a noticeable reduction in cruising speed🤣.
Look at it in these term. When you have a beverage package with included gratuities you will still incur an extra gratuity when you order a beverage of a value higher than the limit. If you get a continental breakfast you pay nothing. Any other time it is an upcharge so a gratuity applies.
No credit. The cruise will be repriced at the then current promotion. Any perks/extras you had will disappear and you will only have the new fare and promotions in effect at that time.
In Grand Cayman all I do now is get on an early tender, snap a pic or two of the ship, as shown, walk a short bit, get back on a tender and enjoy the quiet ship.
