Swim Shoes? Any recommendations?

Ok, I need a pair of shoes that I can wear on a wet floor surrounding a swimming pool in a motel. Last weekend, I didn't have any, went barefooted in the pool area (and the floor was smooth tile), and ended up slipping in the water and falling flat on my face (well, actually, it was my chest, those boobs are good for something, they kept me from breaking my nose on that damned hard floor). Banged up my bad knee (as usual) pretty good too. So I need something other than thongs (I've worn them on wet tile floors and slipped and slid). Are there swim shoes that are made just for walking on slippery-when-wet tile floors? Would Crocs (or something like that) work?
I wish the motel we stayed at had a floor around the pool like the one in Rogers, MN. That floor had tiles that looked like pebbles had been embedded in cement, and it was rough to the touch, so when it got wet, you didn't slip and slide all over the place. I let the front desk know that they really needed to put a sign on the door, warning people that the floor was slick when wet (they said they had signs in the pool area, but I didn't see any, and I read the signs when we first went in (all about how many people were allowed in the pool [49] and how many could be in the hot tub [10] and that there was no diving in the pool, but nothing about a slippery-when-wet-floor). I know, it's just common sense that smooth tile floors are not the safest surface on which to walk when they're wet, and I was being careful, walking slowly, and trying to hit the dry spots, but I hit a puddle of water and bang, down I went. So I told them they might want to think about finding some way of either roughing up the tile so it's not quite so slick, or getting some of those black, sandpapery strips that you put on steps so they aren't slick when wet (yeah, like they're going to listen to me).
So now, if I'm going to be swimming at the pool here in town (their floor is the smooth tile), I want shoes to wear in there that won't slide on a wet floor. My rubber-soled sandals won't work (I've slid on a wet floor in Wal-Mart while wearing them).
And just in case you're wondering, my knee is fine now (ice on it that night took down the swelling, and ibuprofen killed what little pain I had). I just don't want to fall on it anymore, I've done more than enough of that in the past.
