Plz recommend ridiculous drinks w/ umbrellas in them

[Howard Beale]

So, I'm taking my mom to The Palms in LV at the end of May. They offer a free night when you purchase 2 during selected weeks and it makes for a nice bargain because you can get the rooms much cheaper and The Palms is a pretty nice place.

Anyway, THIS time I am not going to play poker or do any kind of gambling at all, not in the least, none! It'll be dinner at Delmonico's and The Phantom, shopping and the comedy show at the Trop, which by the way, is a great show for $20 and you should check it out. Mom will play the Wheel of Fortune and sneak off to play the Megabucks when I'm not looking even though I tell her only 2 people a year win it but she says that means she has a chance.

Anyway, part 2, I'm actually going to spend a good amount of time at the pool at The Palms. I've seen a couple of pools in LV from my hotel window and once, in 1995, I went out w/ swim trunks on and almost went in the pool at the Mirage but I only lasted 5 minutes and then it was back to the craps table in my flip-flops. So I was thinking that while laying out at the pool at The Palms I can order drinks from those really young, incredibly hot honeys that they have working as attendants but I don't want to drink my regular drink (Grand Marnier) because that is not a suitable drink for lounging at a pool, I don't think. So I figure that this is the time to try some of those absolutely comedic looking drinks that you see in the movies sometimes that always make everybody laugh. The ones in the coconuts w/ the paper umbrellas and other ornamentation hanging out of them, but I don't know what any of them are called or if I'll like them or not so:

If any of you folks know the names of some of these silly drinks (the more outrageous the better) I'd appreciate you letting me know and also what they taste like and how many I can drink before I become dysfunctional. For references' sake I get that way after 6 Grand Marniers in an hour.

Thanks for the help.
