We're going on our first Disney cruise in April! 5 day western Caribbean on the Wonder. How early can we get to the port of Miami? I've read 11 but then saw some posts stating people get to the check in at 10:30am. Also how long does the check in process take? When can you board the ship and what is there to do between checking in and boarding? Also where do you request an upgrade and any tips on that? Thanks! This board is awesome and I've already picked up a few handy tips. We're park veterans (my first time was to MK in summer of 1972) but this will be our first Disney cruise and DDs 8 & 10 first cruise.
