I am going to Disney world from August 13-21 for a Disney world trip with my 2 grown children. I was not planning on renting a car unless needed. A couple of questions. First, is the shuttle service provided by the JW Marriott good enough to use for transportation instead of renting a car? Second, has anyone stayed at this hotel? I know it is a newer hotel and have stayed on property every trip to Disney world until now so any thoughts on the hotel as a whole? Am I better off at an onsite hotel. I got a decent rate here (about $225 per night) so a comparably priced onsite property is probably the Pop or Art of Animation I would think. Thanks for your input and thoughts!!
