I booked my activities last night at 12 EST, as I am 90 days out. I didn't want to wait until 3 am to check in, so now at 8 am I keep getting error messages when I try to check in. Is it me or is it the DCL website? I am doing DCL transportation. We fly in the day before, stay at an airport-area hotel and use the hotel's free shuttle to go to and from the airport. We can arrive to MCO after breakfast and make the first buses. Is is absolutely imperative that we chose the earliest port time, or does arriving on the DCL bus allow us to arrive "whenever"? On a side note, we were able to schedule our specialty dining and nursery times as we wanted it!!
