Thanks for all of the replies. I can see my kids towing their luggage

year right.
I thought the Marriott was a hotel on property like the one at MCO but then I read "shuttle" and thought to check it out.
The Marriott is $75 more than any other property and if we have to shuttle, probably not worth the difference.
We used to be Marriott people but got turned off for a few reasons and now we use Starwood properties. I'm booked at a Sheraton Suites next week at PHL so we'll see how that goes.
