During the very first sailings on the Disney Wish, getting into Hyperspace Lounge was just about as big a feat as getting a Palo brunch reservation on an at-sea day. Well, maybe not that drastic, but it sure felt like that to me.
Anyway, passengers wishing to visit Hyperspace Lounge would need to immediately go to a specific location aboard the ship, in this case, Luna, in order to try to secure a reservation during some point of their cruise.
Effective immediately, cruisers are no longer required to make a reservation in order to enter Hyperspace Lounge. We should note that the space is currently limited to 45 people. As with anything, Disney Cruise Line could change this at any time, but for now, folks are able to enter without a reservation as long as space is available.
