If I can do a day of Sea World :)

Then a dinner party should be a cake-walk (no pun intended) :) It wasn't always easy, but I just made some aid in a 33 liter Figi bottle and sipped it all day. I also took another liter of water to sip on and finished them both before we left the park. You know what though -- it was interesting to watch how MUCH people eat. I never really noticed before -- it was pretty humbling.

Good luck - you can do it!!!
