I am considering the key for a 4 night on the Indy to get early embarkation. Is it worth it? is Port Canaveral really that strict with embarkation times? for reference I am Diamond Plus as well, but for 4 nights I want to maximize every second of the ship...and drink package lol. I am planning to buy internet anyways and they key is only a few dollars more a day and includes internet....so why not get the key??
