I've been to Vegas numerous times and have stayed at Alladin, Mirage, Treasure Island, and Excalibur. I have had a suite at Treaure Island and Alladin. I have also been in just about every hotel that is on the strip.
Excalibur is inexpensive, but very much like a room at Holiday Inn. Alladin was a beautiful room, and is is a pretty good location and has it's own "mall" of stores attached to it. Mirage and TI are probably my favorites, they are both very nice rooms, are attached by a people mover and are easy to get around from.
If you go to Vegas.com you can not only compare prices, but also see maps of layouts in Vegas and compare amenities. I am a huge fan of this site! Once you compare the prices, call the hotels you like and ask for any specials. That is how we got suites for the price of regular rooms, sometimes for less.
I live in So. Cal. and my fiancee and I used to go to vegas about once every 6-8 weeks.
There is so much to do in Vegas and I love it there! If you have any questions, feel free to PM me and I will try to answer.
Also, if you plan to see any shows, Blue Man Group is fabulous and Jubilee is unimpressive. And don't miss the Pirate Battle at TI!
HTH!
