We stayed next door at the Hampton inn and suites and it is NOT walking distance, especially with a double stroller with two kids in it and bags, etc... The great thing about the ART and the ES-south is that it is a straight shot to the hotel from the park, no stops. There is only 1 stop on the way to the park and I don't recall us ever picking anyone up on the way. Its a great hotel and great location but you'll be drained trying to walk it...If you do decide to stay off site, I would highly recommend one of the hotels in that parking lot because Art was fantastic there.
