Hi to all experienced cruisers. I want to know more about check-in and boarding. I have read that it is advisable to get to the check-in early. What time does check-in begin? What time is "early"? Also, once you check-in are you obligated to stay in the terminal until boarding, or are you permitted to leave and return later to board? When do the busses from Disney arrive? We are staying at the Radisson at the port and thus have the ability to go back there between check-in and boarding, if permitted. Any other tips or advice would be greatly appreciated!
