Dress CodeFor lunch, Guests may come in fashionable casual attire in order to enjoy the Disneyland Resort in comfort. However, no tank tops, cutoffs, swimsuits, bare midriffs, sweatpants, flip flops/sandals or beachwear may be worn. Walking length shorts are acceptable. Jeans are acceptable, provided that they cover undergarments completely and are not extremely faded or torn.If Guests have been enjoying the day in Disneyland Park, evening casual attire is acceptable for dinner. For gentlemen, collared shirts and slacks are appropriate, and for ladies an informal dress or pants with a blouse are appropriate.(Update: The club is no longer accepting shorts of any type or style for dinner.)Appropriate dress for children and young adults should be in keeping with standards set for adults.
I would think country golf club attire. Not sure I would do jeans. I wore a skirt at lunch and felt fine. IMHO it is far worse to be underdressed. Err on the side of caution.
Enjoy and happy anniversary!
