BTW, you CAN use your sail and sign for the casino...just don't forget to pull the card out like I did. Thankfully, a good samaritan turned it in for me.
FYI, I found the Bursar's Desk to have an extremely long line day 1. Hopefully you can avoid it! I used cash to set up my sail & sign and had to wait in this line to do so for quite some time. I'll be using my credit card next time.
I've only sailed a couple times, but I do remember both times I didn't pack a sufficient carry on. You won't see your suitcases for a while so pack the swimsuit, suntan lotion, camera, necessary meds, etc...AND, don't over pack it because you will be lugging it around until you have access to your room.
It's so exciting pulling away from the dock, enjoy it! All the boaters around you will be waving; they are use to the cruise ships coming and going.
I hope you have a really nice time!
