Hi Diana,
This is a tough decision - a one bedroom villa at
Disney's Saratoga Springs Resort & Spa or a Club Level room at
Disney's Polynesian Resort. Disney's Saratoga Springs Resort & Spa is themed as a horse-racing resort in upstate New York in the late 1800's. If you decided to stay in the one-bedroom villa at Disney's Saratoga Springs Resort & Spa, the amenities that you have in a one bedroom villa are great. You have a full kitchen, as well as a washer and dryer right in the room. I use both of these often when we stay in a one-bedroom villa.
The location of Disney's Polynesian Resort is amazing, being right on the monorail line. As you know, the theme and atmosphere there is absolutely beautiful. The lush and tropical theme is amazing and immerses you in the feeling of the South Pacific. At Disney's Polynesian Resort Club Level, you will have access to the Club Level lounge, which offers snacks and drinks throughout the day and is lovely. You will also be able to work with the Club Level cast members in your planning. You should know that Disney's Polynesian is currently undergoing renovations, and that these will likely extend through the time that you are going to travel. You should consider if some construction at the resort will bother you.
If I was traveling in a party of two adults and making this decision, I would chose the Club Level at Disney's Polynesian Resort. Though I absolutely love the convenience of a one-bedroom villa, I find those conveniences to be more important when traveling with children. I hope that these thoughts are helpful for you in making your decision, Diana. Please do not hesitate to ask if you have any further questions!
