Hi Jane,
How wonderful to be taking your grandchildren on their first trip to Walt Disney World! I think that
Disney's Saratoga Springs Resort & Spa will be a great place to stay for this trip. The extra space and amenities in Disney Vacation Club villas make vacationing with little ones so much easier.
There are a couple of factors that might impact where you would like to stay at the resort. Because you have little ones with you, and especially if you do not have a car, you might want to request The Springs area. This area is the closest to the main lobby, as well as to dining and the High Rock Pool. Disney's Saratoga Springs Resort & Spa is lovely and quite spread out, so if you are in other sections that are further away from this area, it might take a while to get to it. Especially if you plan to take advantage of the High Rock Pool and restaurants, a nearby location will probably be nice. Because The Springs is the closest to these areas, it can be a little noisier. For a quieter room, you might consider asking to be on a higher floor. Another section that might work well for you is The Paddock, as The Paddock Pool is located in the area, as well as a quick-service dining location. Please do note that while Disney will do their best to honor any room request, they are only requests and are not guaranteed.
I hope that this information is helpful for you, Jane. Have a great time planning your trip, and please do not hesitate to ask if you have any further questions.
