The first time I went to Vegas was in March and yes the weather is best at that time year. Not too hot and not cold at all.

Definitely check out the Stratosphere rides at the top, you may not want to do all of them because there is one that might make you soil yourself. Bellagio fountains are pretty cool at night along with the Fremont light show.

If you are looking for something low-key, I recommend the dueling twins piano bar over at Harrah’s, which is also where they sell the 3 foot margaritas w/shoulder straps. Walk around with those on the strip and you get the looks and conversation starters, “Where did you get that?!?”

For St. Patty’s day, the NYNY irish pub is cool and I think the Orleans has an Irish Pub as well, which is really nice. I’ve never been there for St. Patty’s day, but I’m willing to bet that it gets less crowded than the one at NYNY, unless that is what you are into.

Penn and Teller is a great show at the Rio but a lot a big name shows are kind of pricey. I think I remember seeing their show for $75. If you are willing to spend the money and see if you can get tickets NOW, the Danny Gans show is the best show in town.

If you are a big fan of lobster and crab legs, the Rio is the place to go but it is like $40 per person. The Bellagio is the best for a Breakfast buffet.

The Monorail is definitely the way to travel between casinos. Cab fare adds up and traffic is kind of horrific all over Las Vegas.

Every cab and monorail should have like a book or magazine that lists all the entertainment options along with coupons. Browse through those and pick what you want to do. There is so much that you won’t be able to do it in 4 days.
