Just got matched with Marriott Imperial Palms through Interval for next April. There will be a total of 8 of us, 2 families. Debating on if we should rent cars, or just plan to use rideshares. We will do Disney for 4 days, and Universal for 2. From a price standpoint I don't see much difference once you factor in all costs. I realize the convenience of having your own car, but this being our first time off property maybe there is something I am missing? We will use grocery delivery services prior to arriving, and we eat mostly in the parks.
