Hi Liz! Welcome to planDisney! Thanks so much for stopping by our happy website with this great question.
Celebrating birthdays at The Happiest Place on Earth is always extra magical! I'm happy to hear you're staying at
Disney's Grand Californian Hotel & Spa for your son's special milestone. The amenities at this beautiful hotel, such as the pool and parking are reserved for registered hotel guests listed on your hotel reservation. I do have an idea though about how your family can join you to celebrate! If your family has an
Advanced Dining Reservation, they will be allowed to
self-park or valet at the hotel for an hourly fee. I recommend they make a reservation at
GCH Craftsman Bar, located right next to the pool, and request a table that is poolside so they can be part of your special pool day.
Be sure to ask the front desk at the hotel for a birthday celebration button for your son! It makes a great souvenir, and it's complimentary. Cast Members love to wish guests a "Happy Birthday" too, which will add lots of fun to your celebration!
I'm wishing your son a very Happy Birthday and hope you make many magical memories during your Disneyland Resort vacation! I hope you will stop by
planDisney again when you're ready to plan another
Disney Parks vacation. We would love to help!
Happy Planning!
Smiles,
Lisa
