Do not bathe in perfume... but please bathe in your hotel room once in a while! I look like an idiot when I have to leave 8 feet of space between me and the next person in line because my nose can't handle thier emmanations.
Treat people in
ECVs and wheelchairs with some slack. Those things don't always stop or turn on a dime. Ditto for strollers.
When you're in one of those things, practice with it a little before you go to the parks. Those things don't always stop or turn on a dime. Ditto for strollers.
Taking a few minutes to rest, look at your park map, talk things over with your group, and decide where to go next is an excellent idea! Just don't do it standing in the doorway of an attraction, restaurant, shop, or bathroom. Other people need to get in and out!
Smoke in the designated areas, please. I know, you have a right to do as you please, but you do not have a right to force me to do it, too. And by the way, when you're in an attraction line, holding the smoking material down at your waist in a cupped hand does not hide it from anybody, it just increases the chances that you will accidentally burn somebody through your carelessness.
Please make your 2-year old walk in front of you while in public, not trailing 20 feet behind you where you can't see them and they can easily become lost, stolen, or get into mischief because you're not watching. You do love your kids, don't you? Then at least keep ONE eye on them in a huge crowded public place.
I know that there are CMs paid to clean tables and toss trash in the counter service restaurants, but try not to make too much of a mess of your table anyway. The CMs are already spread way too thin; having to spend 20 minutes cleaning up trash and spills from one messy group means that much less time they have to clean the rest of the dining area.
Say please and thank you to the CMs. They work pretty hard to make your vacation pleasent, the least you can do is be moderately polite to them in return. Paying a lot of money for your vacation does not buy you the right to treat the 'little people' like, well, little people.
And above all, RELAX! It's a vacation, not a millitary operation. Schedules are not set in stone; be flexible and go with the flow once in a while. Don't sweat the little stuff. If you're trying to have a good time, you won't have a good time; just let it happen and you'll have the best vacation ever.
