High Seas Rookie

My cruise is next week. My travel agent gave me a onboard credit as a booking perk. When i log into myNCL account, i noticed there is a new On board Credit Certificate under purchase items in my vacation summary. I guess this is from my travel agent because the amount is the same. On the delivery date, it says December 30. My cruise date is November 11. I guess my travel agent put the wrong date. Will there be a problem?

When I view my booking, Isee I have $50 dollar on board credit. I am guessing it is going to be splitbetween me and my travel partner because it shows up in my vacation summary asFree $25 USD On-Board Credit Certificate Non-Refundable QTY 2. Whathappens if my travel partner does not use up all of the credit and there islike a few dollars left over in her account? Does it roll over into account,can I combine it with my account? At checkin, we will be using thesame credit card

Do you have an accessibility concern?

i have very bad knees, i cant walk up/down stairs. i can do a few steps here and there

on which deck do you board the tender boats? is there any stairs from the ship to the tender boat? I seen some videos on youtube about tendering and it seems there is a small platform on the side of the ship you have to walk down. does great stirrup cay tendering us this platform?

I see by the terminal, there is a lot of horse drawn carriages. how much do they charge, how long is the trip?
