Questions for my 1st trip to VEGAS

[Action Scott]

I have searched through some older posts and found some good info, but still have a few questions for the vegas regulars.

1. I will mostly be playing less than $100 buyin NLHE tourneys, I have the list in the back of cardplayer, but would love some suggestions for the best ones to play from those who have (blind structure, staff quality..etc.).
2. I would also like to play in some Omaha H/L cash games, preferably 3/6, 4/8 and maybe 5/10, which casino(s) have these regularly? I would prefer to not play w/ the Kill, but I understand most casinos that spread O8 probably use it.
3. I am staying at Excalibur, got any info on it good or bad?
4. I am going w/ my friend and our wives, we wanted to send them to a spa for a masage/mudbath/whatever the hell they do, is there a decent on to send them to w/ about $100?

I will be there from Oct. 23-26 for what it's worth. Thanks for your help.
