Utah has a teacher's convention on Oct. 12 and 13 some schools also have Monday the 16th off for a teacher work day. We are from Utah and we are going to DL and we know lots of other families going also. I hear it is really crowded during that time from others who have been during UEA or the Utah teacher convention. Most teachers don't go to the conference they go on vaccation as they don't get any other fall break. In fact my husband is a teacher and we are headed to DL. We chose crowded and better weather than to go in the summer with crowds and heat. Sounds like all of October is going to be crowded though with the new Halloween time drawing lots of vistors. Lots of Arizona schools have Fall break during the same time as Utah's break, it sounds like a lot of people of Arizona will be there too.
