Very doubtful they will remove a piece of furniture for you. Their response will be "we have no place to put it". Extended family experienced this once on Radiance.
Lot's of kids cartoons on the in cabin TV. However we bring our firestick and for the last several years have been able to watch Netflix, Amazon Prime etc etc. on RCI ships streaming them. This has been very easy to do.
We've cruised Alaska 5 times with RCI and our very first cruise there we had no excursions. Of course that has changed over the years but the first time there we were just fine with the cruise ... views and just the fact that we were in Alaska.
Take one of the shuttles into town...easy to do and when you're ready to head back to the ship just hail down another shuttle. Should be $5.00pp each way.
Very unlikely you will day port at the Pan American pier. We stay at the Old Town Sheraton often pre RCI cruise which is across the street from Old Town and have seen NCL many times day porting there.
We get the GeoBlue Trekker policy...haven't had to use it yet but very happy with what it covers. Also in our mid 70's and found it was the best option...easily purchased it and renew it online.
I would stay at a Fort Lauderdale hotel and use one of the many private shuttle companies offered to POM from there. Try Hyatt Place booking through ValueTrips or as a Hyatt member for rates.
