They have several locations set up within the parks where you can show your resort ID and get a wristband. We found the Evening EMH, (Sept.14) at the MK to be WAY more crowded then it was during the day. We walked right on everything during the day but there was at least a 30min. wait on most rides during the EMH. There is only one park open that all the resort guests want to go to, instead of having them spread out among the four parks.
