Gaining

Increasing capacity without overdoing it to prep for a trip

My wife and I are going to be going on a trip to Disney in about 6 weeks and I know that Disney has quite a few "all you care to enjoy" restaurants. I was wondering if anyone had any advice that would help with increasing capacity so that I can get my money's worth at these buffets without overdoing it to the point where I'm uncomfortable in the weeks leading up to the trip? I'm trying to be more balanced in my approach to gaining since it's definitely not fun to eat until I feel sick and can't eat for a day or two, but I also want to have a bit of fun with it.
