There are lots of businesses, small and large, who have memberships at Club 33 in DL. I’ve been the guest of one. Yes the food is amazing, there are often charchters in there. You can watch the fireworks or Fantasmic from the balcony. You can go back up to the club to relax and have a drink any time you want during the day you’ve been given guest access. It’s an awesome experience, partly because it is so exclusive that it is so exciting and special to get an invitation to get in. I hope they continue that tradition with what they build at WDW.
It was originally designed as a place for Walt to entertain VIP’s and not intended to be something any random family visiting would buy into. Corporations, celebrities, etc. DL has had such a long waiting list at times it’s been 10 years to get an invitation, I don’t know what it is now. It is not for everyone, not intended for the average traveler. People saying it’s too expensive or not worth it, it wasn’t built for you ;-)
