Hi Pat.
For the 4 people on my list who paid for "event only admission" I have submitted those names to the catering manager at WDW. Those people will need to meet at the front entrance to Epcot (not the International Gateway). There will be a person there carrying those "light saber" looking sticks that will have your names and will escort the group to the party at the UK terrace. If you have any problems locating the correct person, go to the guest services window and they should be able to radio someone to meet you.
For anyone who wants to keep this information on hand, the party is listed as the "Marathon Group Dessert Party" with me, Rhonda Hare, listed as the main contact. The event is taking place on the lower UK terrace (just to the side of the Fish & Chips take-out area in the UK pavillion). Our catering manager is Sue Smith. You can call me on my cell if you have a problem that night at 214-334-6807 and I'll do what I can to help.
