I did a 3 night/7 night on the Wonder feb 2018. Same room both times. I really saved on parking! We have done a b2b every feb for the last 4 years. Always Magic or Wonder....always same cabin, normally oceanview deck 2. Yes, we’ve always had to wait to get back on but normally it’s been 45 minutes or less. Yes some folks leave and do a-day trip in Port Canaveral, but you would have to pay to park again if you move your car. There will be instructions and a boarding card the day before. Your dining team will know and the head server will speak with you regarding keeping your dining team. We normally are at a multi table on part one and ask for a private table on part 2. In the past we have always been told to gather and meet in one of the clubs until the ship is cleared, then we are escorted off and back into the terminal to check in. Often that part is slow as they usually only have 2 windows open. When you get back on the ship, the pools are not open, but you can get some coffee at the cove. Some folks do laundry, but we go and find lounge chairs and relax. This past February it was raining so we gathered in the lounge and chatted with fellow cruisers.
