This year marks my 16th straight March Madness trip to Vegas. A couple of observations:
* I am a low roller, and rarely play any tables above $5. You can almost always find $5 tables at the south end of the strip (Excal, Oyo) and very rarely center strip. (They do usually have $5 3-card-poker at the Linq, and maybe $10 craps, pai gow or UTH at Harrah's).
* A very valuable resource is the March Madness in Vegas Facebook page. They post reviews of all sportsbook watch parties and special deals available only to FB page members (like $25 match plays at the D and Golden Gate). But if you want an all-inclusive watch party, prepare to pay through the nose and act quickly. My crew has never found it hard to find a place to sit at free parties off-strip and downtown, or just sit at the bar playing video poker and watching on the bar TV.
* Everything is more crowded Thursday and Friday, but things actually start to calm down a bit on Saturday. (I assume people run out of money or are so hungover after the first round is over they don't make it out of their rooms.)
* If you're betting the games, the best option is probably to get the app. The lines at the sportsbook will be VERY long until after the last games start on each day. The problem with using the app is no free drink tickets; but those are hard to get during MM anyway, unless you're also making horse race bets.
Have fun! MM is a blast, and I can't imagine not going.
