First in, best dressed! It's a first-come, first-serve situation.
If you've booked more than one (1) bed, the first to arrive must communicate with the staff to see if the bed next to your chosen one can be reserved.
If you're all arriving at the same time, you can just pick beds that are right next to each other. No one needs to break up for the night, but we do recommend you arrive early to make sure you get spots next to each other. You can claim your bed, leave the premises to take a stroll around the promenade, then come back closer to the movie time.
