Rules for enjoying Fall Break at Great Wolf Lodge and Indoor Water Park in Texas:
Rule #1: When you invite your mother to go with your family, since your husband can't go (pesky darn radiation treatments ....) make sure she actually realizes you are staying three days, and not two. Otherwise there might possibly be a clean underwear dilemma.
Rule #2: There is no graceful, lady-like way for climbing into the back half of a two-person float tube. Just spread your legs, pull down your swimsuit, go for it and enjoy yourself without shame.
Rule #3: When your brother-in-law climbs the stairs to ride the same toilet-bowl slide that you are already in line for, and he's four or five people behind you, do not turn around and say "Hey, good looking" unless you want the gentleman in between you to assume you are talking to him. (Funnily enough, he didn't appear to know whether to be flattered, or horrified.)
We have 48 more hours to go .... I'm sure plenty more rules will be forthcoming.
