I have a few:
1. I never realized that you did not have to just eat at your resort until the day after I arrived.
2. If you see something you really want, get it. Case in point, also first trip in 2000, a combo purse and clutch by Dorney and Bourke. All my favorite colors and matched every polo shirt I owned at the time. But at the time, the cost was a lot to me. Now that thing is gone and before it did, the price was twice what it was when I first saw it. I still think about 12 years later.
3. When you travel with smokers, let them know the rules from the very beginning.
In 2006, I invited 3 friends from work, two of us were non-smokers and the other two were heavy smokers. That was one of the last years you could request a smoking room, but I booked a non-smoking room. I had paid for the room (I normally go solo,so had already paid for the entire thing) and they split the extra adult fee. I figured we would all agree we did not all have to smell like smoke. At check-in, Sarah threw a hissy fit and insisted they change our room, but they were already booked solid due to a competition. She insisted we find a room at another resort or she was going home right then and there. In hindsight, we should have let Sarah go, but Linda, the other smoker diffused the situation. We got a room facing the parking lot and they smoked right outside to their heart's content,......until we hit the parks and explained the smoking areas.
After two days of planning our entire day around Sarah's smoking - ride one ride, get to a smoking area and stay there for several hours, ride two more rides, three hours of smoking, etc., we were pretty bored. The other non-smoker, Donna, and I finally went off on our own and Linda appeased Sarah by hanging out with her.
We had arrived Sunday and Tuesday afternoon, we were in DHS doing our thing and Linda called and asked where we were, because she wanted to catch up with us. She showed up alone, said Sarah was continually reprimanded for walking around the park with a cigarette between smoking areas. Linda was mortified, they had a huge argument, and Sarah was going back to the resort, packing and going back home. Luckily, we had flown SW, at her insistence, so it worked out well.
When we returned, she acted like nothing had ever happened.
