Oh no, no wrist bands anymore. You each have to show your room key. You could save a lot of time by having 4 of you "lose" your room keys - they are so accomodating at the front desk to get replacements! Then you all can ride at the same time, but you had best use the accessible entrances to make sure you all get on together! One of you could rent an EVC (split eight ways, it would be worth it) and they won't question it at all.
Thanks, we'll do it your way!!!
