Hi there,
We were on the Majesty of the Seas last September and it's a lovely ship. It was our first experience of cruising and it's given us the bug now!
I agree with hamrag - there's not a lot to do in Key West, although it is lovely. Definitely do the Conch Train - it's a sweet little overview of the city - and do it first so you can visit the key sites. We also wandered round the harbour and went to visit the little conch nursery nearby (small and cute!). Also, try the Key Lime pie and, if you're feeling adventurous, the conch fritters - both are scrummy!
Nassau was our first port of call and we were really disappointed! It's a grotty, dirty little place and we didn't feel particularly safe. However, take one of the boats from the harbour over to Paradise Island - the boat fare is really cheap (about $5 each return) and you get a bit of commentary on the way. Paradise Island is beautiful - a world away from Nassau. Again, there's not an awful lot to do, but we visited the huge Hotel Atlantis on the Island and just had a nice wander round, a paddle on the beach etc. There's a fab ice cream shop there too which has every ice cream known to man!
In Nassau itself we did a horse and cart tour, but it's not really worth it for the money (something like $20 each plus a tip). If you like shopping, apparently Nassau is the place to be, but we aren't shoppers so that's probably why we weren't impressed!
Hope that's helpful. Enjoy it - we certainly did!
