You can't really 'avoid' the booths - not standing in the lines to get stuff from them is one thing but the people are still everywhere, and they will still be doing the regular things, like going in the shops, watching the shows, and doing character meet and greets. I went on the last day (Sunday) both of the last 2 years and it was pretty crowded. Big lines in Mexico, Germany, America, Japan, France, and Hawaii booths. Still fun. They will not have the passport books though - those are gone by then, and a lot of merchandise was gone as well, but I don't recall any food or drink items being removed from any menus.
