We've been lucky enough to go twice. Rick and I used to take our nieces to a theme park every year on their birthdays (which were a month apart) when they were kids. As adults, one of them had access to the club and they surprised us with a trip to Disneyland which included lunch at Club 33. Our other trip was with a dear friend on her birthday. Turned out the club member who arranged for that visit, unbeknownst to us, paid for all our food and drink. Quite the nice surprised.
So pleased you were able to enjoy this icon of Disneyland. Now you'll have to wrangle another invite after the remodel is done to see the changes they make!
