I've always heard 3 hours and have been told that specific timeframe by some guards in the past, but we there a couple of weeks ago and weren't given any limits for the resort meals where we drove. The only special instructions we got were at the Contemporary, and I was told to park in a specific area because they had an event going on that day. I would have loved to park there all day because it's a pain to drive back through the MK entrance and park at the TTC...especially since 7am traffic and 8:30 am traffic going into the park entrance is vastly different. Still, we did it...because my luck I'll get towed.
