I am not an expert by any means but I have been looking at DTD hotels as we are a party of 6 as well. The Doubletree is an all suite hotel and can accommodate 6. The Best Western has suites as well and can accommodate 6 as does the Buena Vista Palace. The only DTD hotel that has EMH is the Hilton. You have to pay the daily parking rate at the parks, it's not included with DTD hotels. HTH some.
