We've dealt with the Germans in Mexico (Puerto Vallarta). They could be a treat. The rude ones down there seem to come from Central and South America. Although I do remember one large rude family from Chicago, but we hate them back here in WI just as much as when we're traveling.
I'll probably just start pulling towels off the chairs and putting any personal stuff they left on the chair up on the towel return along with a copy of the Navigator with the "seat saving policy" highlighted. (note to self: remember highlighter) But then again, I'll probably chicken out. But if it is like last time, there was NO ONE at the pool until almost 9:00 on sea days, so no one would see me.
I think the entertainment will be when the people come back and see their stuff moved. Just have to make sure I'm not sitting in or near their seats. If you see me at the pool when you come up, ask me which seats are "safe" to sit in (i.e. non-removed item seats).
I figure I'll be up there with Nancy, Cass, Karen and all the other nocturnal KKers. DIS meet every morning at 7:00 at the Mickey Pool.
