Several questions you should answer to make your Vegas adventure everything you want it to be.
WHY Vegas? What do I want/expect of Vegas? What is my overall total trip budget? How long will I be there? Do I need a car? Will I visit the "other" attractions, Hoover Dam, Red Rock Canyon, Grand Canyon, etc?
Do I gamble? Slots? Poker? table games? VP? Is my gambling purely "recreational" or do I think I will win because "I have a system", "I studied and practiced at home on my computer", "I'm an experienced player and know what to expect in a casino", or something like, "I might play one hour per day"?
Are you looking for "deals", or is the budget one where expensive meals, etc don't matter? Are you "willing to work cheap" in order to get free money or free bets by visiting many casinos?
Only you can decide. Once "we" know what you're looking for and expecting, than it would be much easier to give good advice based on your expectations, wants, and needs.
One thing I will mention. When you calculate your all inclusive trip budget, include your gaming bankroll as a separate number. Than double or triple it.
It is also possible for "newbies", and even veteran visitors, to "gamble" many hours with a minimum bankroll. Almost every casino gives new player club members something.
And the "coupon books", specifically ACG, LVA MRB, and fun books all have "free money" type coupons.
I am probably the most "frugal" on the various Vegas forums. I am a "casino whore", and I do not "gamble" without a coupon or promotion, with the exception of live poker or video poker.
Many would say that does not sound like fun. For me, it is. And my Vegas trips pay for themselves. BUT, it is definitely not for everyone, and requires a tremendous amount of pre trip planning, and all the Vegas forums can provide useful informations.
Just spend time reading and learning and asking.
