Hi Matt,
Thanks for visiting the Disney Parks Moms Panel with your question.
There are not adjoining deluxe studios at
Disney's Saratoga Springs Resort and Spa; however, you could request deluxe studios which are near to each other. To do this you can call the resort within 10 before your arrival to have the request noted on your reservation. The phone number for Disney's Saratoga Springs Resort and Spa is 407-827-1100. Please know that Disney will do their best to honor any requests; however, a request cannot be guaranteed.
Another option for you might be to do a two-bedroom villa. The two-bedroom lock-off villas are essentially a one-bedroom villa and a deluxe studio which have a connecting door, which you can close to let each family have their own space. In a two-bedroom lock-off villa you will have two separate entrances. This is different from a two-bedroom dedicated villa in that a two-bedroom dedicated villa only has one entrance. Either a two-bedroom dedicated or a two-bedroom lock-off villa would give you more space than two deluxe studios, including that you would have a full kitchen as well as washing machine and dryer. If you decide to go this route and have a strong preference for a lock-off or dedicated two-bedroom villa, please be sure to indicate this at the time of your booking.
I hope that this information is helpful, Matt! Please do not hesitate to ask if you have any further questions. Have a great time planning your vacation.
