We were on the Wish last month on a sold out cruise. No reservations needed. We went 3x (once during the day with kids, twice at night), not close to capacity either of the evening times. Bartenders were great and we enjoyed the view of various different planets in the Star Wars universe. The cocktails are also a lot of fun and husband said the beer is good. If you are or have ever been a Star Wars fan, I highly recommend it for a short visit.
