I am hoping someone can tell me what the requirements and downfalls are for purchasing YES tickets. I have chaperoned a senior trip and used them and loved the class, but thought they were just for youth groups and had no idea that my family could also purchase them until recently. They look like such discounted prices that it is too good to be true. We hope to use a room only discount so we aren't looking for free dining so we don't need to book a package with regular tickets. Any info to help me about how the YES program works for a family of 4 with DD11 and DS6 in November would be appreciated.
