We just got back today! The deals there are wonderful. First, the airfare was cheap.
Second, the room rates are really reasonable (We stayed at the Monte Carlo, but most places on the strip are running at special rates right now).
We picked our moderate to pricey meals out- Gallagher's at NYNY, Trevi at Caesars Forum, Mon Ami Gabi at Paris but balanced that with food courts at Monte Carlo (McDonalds, Subway, Sbarros, Starbucks, a Chinese Restaurant and a Mexican Restaurant for choices, and at the Venetian they had a wide variety of vendors at their food court - Arthur Treachers, Nathan's Hot Dogs, Johnny Rockets. I am not sold on the quality at the food buffets, but at the Excalibur they had an eat all day buffet for $29. There were many 2 for 1 offers. Take the booklets from the taxis and the other coupon promos.
There is a CVS Pharmacy next to the Monte Carlo. We stopped there to pick up water bottles and a Pepsi six pack as well as donuts for breakfast. They also had snack items and fresh fruit.
Transportation: We always take the taxi from the airport to the Hotel. Seems to cost more if they take the highway rather than Tropicana Ave. to Las Vegas Blvd. I am too impatient to wait for other modes of transportation when we first get in.
The double decker bus is called the Deuce and runs 24/7 on the Las Vegas Strip. They are about 4-5 minutes apart, except for after midnight for a few hours when they are 10 minutes apart. Really- it's been tested by us.They only accept exact change, but you can buy passes at kiosks located along the strip (we got ours outside MGM HOtel). A ride costs $3 each way. One day pass is $7. We got a 3 day pass for $15 each. That gives you unlimited starts and stops along the strip. Was worthwhile for us. This will take you from Mandalay Bay at one end of the strip to Fremont Street Experience (and the bus terminal) at the other end of the strip.
Lots of free shows: Dueling pianos at NYNY, every casino has live entertainment in the bars that we did not have to pay for.
We used the Tix4Tonight shops as mentioned in the other recommendation. - They have a location next to the big COKE bottle across from the Montew Carlo. Almost all half price tickets. Note that they did have some Cirque when we were there- Mystere and Love only. (But Cirque is running their own 25th Anniversary promo right now- buy a ticket at regular price and the second ticket is $25. No one else can beat that. Check out cirque web site for details. We bought our tickets in advance for Zumanity and picked them up at will call.)
We paid $59 for Bette Midler tickets that were to be in the Mezzanine and we ended up in the front middle of the Rear Orchestra- great seats! If you use them -TIX- (multiple days for tickets, be sure to take your ticket stubs and the brochure back to them the next day (when you purchase tickets for that day) and you can use them for VIP admission for ticket purchase and you will get a reduced rate on the processing fee, which is usually $5 per ticket (not bad). We also got Terry Fador, Blue Man Group, and Wayne Brady tickets there.
Hope this helps a bit. If you need more detail, pm message.
