suprasian when are you going? I'm going back Aug 4-8, was able to get flights from Kamloops
I would recommend checking out tripadvisor.com. Check out the forums. There's a lot in there but it's very helpful. Also just do a generic search on vegas on google and in this forum..
http://www.lasvegas.net http://www.lasvegasadvisor.com http://www/a2zlasvegas.com are some websites I can think of..
visit the bellagio fountains and the volcano (I think at Ceasers). With it being your first time I definately recommend checking out the hotels. The venetan, Ceasers Palace are a couple of nice hotels.
Where are you staying?
here's another site to check out
