Hi Gladys,
Your question regarding the logistics of a "split-stay" between
Disney's Saratoga Springs Resort & Spa and
Disney's Polynesian Village Resort is a perfect one for me to answer as I often intentionally split our vacation time between two Disney Resorts. This makes for an easier decision when selecting among many of our family's favorite Disney Resorts, and also allows us to enjoy the unique amenities and conveniences of two different Disney Resorts during a single trip.
Disney makes it incredibly easy to transfer between two Disney Resort hotels - even if you do not have a vehicle or rental car. On check-out day for your first Resort, simply pack up all of your luggage before heading out to enjoy the Parks for the day, and either call or drop everything off with Bell Services. Cast Members here will ensure that your luggage is transferred to your new Resort by late afternoon. Once you have checked into your new Resort, simply contact Bell Services who will be pleased to escort all of your belongings to your new room. Luggage transfer services between Disney Resort hotels is completely free, although it is customary to provide gratuities to the Bell Services Cast Members who do all of the "heavy lifting", ensuring the safe transfer of your belongings.
During your stay, I recommend you try to schedule most of your visits to Magic Kingdom Park during the time you will be enjoying Disney's Polynesian Village Resort, taking advantage of the close proximity and easy access via monorail or boat. Likewise, try to plan any visits to Disney Springs during your time at Disney's Saratoga Springs Resort & Spa, which is located only a short walk or boat ride away.
Wishing you a Magical upcoming Disney vacation!
Trish
