I know its been done before..help me plan my 1st vegas trip! 21st bday

[DBowling]

Im turning 21 april 9th and plan on heading down to vegas by myself for a couple of nights. The 9th is a saturday, so id like to arrive that morning, stay saturday night, sunday night, and come home monday whenever.
Ill mostly be playing poker. NL 1/2-2/5ish. I prefer nonsmoking cardrooms.
Hotel doesnt matter too much for me, though id like to keep it relatively inexpensive. I know im going to pay a lot for a room saturday night, but if i could average arounnd or below 150 a night, that would be doable.
What should i do while im there besides poker? Shows/clubs/etc? Im a quiet introvert, but ive thought about getting drunk off my ass and going crazy for a weekend.
Right now, excalibur seems to be the front runner. Cheaper rooms, they have a 1/2 NL game. Im not sure if its nonsmoking though.

Thanks for your help!
