As to boarding...last Feb. we got to the terminal about 11:20. We were boarding group 9. We were ON THE SHIP at 12:03, less than 20 minutes after boarding started. So....don't panic over a boarding number.
Only 1/2 of the Palo reservations are available on line. The rest are held back for after boarding. If you don't get what you want in advance, IMMEDIATELY after boarding go to Rockin Bar D (check the welcome aboard Navigator, rarely the location changes), and request what you want. Note...go immediately, not after lunch or whatever. Only one adult needs to go if that matters. The other can take the kids to get Tea With Alice tickets or whatever. If they still don't have the Palo that you want, ask to be waitlisted. (they may or may not offer). The concierge holds a certain number of ressies till the end of the first afternoon, and people do cancel. Waitlists do get called.
7 mile beach break--do it on your own. The
DCL price is a total rip off. 7 Mile Beach is FREE. There is a beach shuttle that leaves from the tender area, or you can take a cab. You can rent whatever you want at the beach, or you can be there all day for the cost of the cab ride. When you're ready to leave, there are usually cabs sitting there. If not, any of the booths will call one for you.
Key West Electric car--can rent them at the pier or reserve in advance from a private company.
Cozumel Scooter--can't help with this one, sorry.
Pirate night is usually movie night in the theater so that the stage cast can be ready for the pirate party and not be tired from doing 2 shows already. NOTE this is not always the case, and on the Wonder they do a show and then do their part in the Pirate show. The Pirate show will feature cruise staff, stage performers, and some of your favorite furry friends.
Definitely bring one "winter" outfit on the cruise as well as a sweater for theatre and dining rooms. December isn't usually cold, but it can be!
