Hey! Christian, and welcome to
planDisney. Club 33 is one of my favorite places at
Disneyland Park because the ambiance, theming, and unique location make it "practically, perfect in every way." The history and mystery of Club 33 have spun tales as old as time at
Disneyland Resort.
If you are not dining with your sponsor (Club 33 member) then I recommend reaching out to them. Ask if they will contact the Club 33 restaurant manager about seating your party with one party member arriving about 15-20 minutes late. Dining at Le Grand Salon is meant to be experiential without rushing over the delicious five-course meal so there likely is leniency for late arrivals if asked in advance. If they cannot accommodate the Club 33 member's request then see if the reservation can be moved to a different time. If you are dining with your sponsor then they should still email the manager to update them on the situation.
planDisney Pro Tip: The souvenirs at Club 33 are outstanding so make sure you pursue the cases for a few keepsakes.
Christian, enjoy many Magical Memories at Club 33.
