This is an off-the-wall question, but do any of the spas in Las Vegas have oxygen bars or, for that matter, are there any oxygen bars on the Strip? A friend and I tried one at the Mall of Americas in Minnesota and loved it. We are coming to Vegas in November so wanted to know if their are any there?

There are so many malls along the Strip: Miracle Mile Shops, Forum Shops, Fashion Show Mall, etc. Do you know what the total square footage of all the malls is along the Strip? I'm sure it must be some absolutely amazing number.

My family and I will be in Las Vegas in late July. Unfortunately, my wife has a problem with heat. What cool things are there to do during the day?

We recently ran a question about TITO tickets and the danger of having them snatched from your machine. We received a lot of interesting feedback from our readers on the subject, so we thought we'd pass on some of your observations and tips.

You get a lot of questions concerning tips. I once heard that "TIP" is an acronym for "To insure promptness" and was generally paid in advance of the meal in Europe. Any truth to this?

We are frequent travelers to LV from the East Coast and have many friends and relatives that love the trip to LV as well. One of the many things we all look forward to is the food. In particular, the horseradish! The majority of our group is of Polish heritage and horseradish is a common staple of the Polish cuisine (as well as Frank's hot sauce). Can we find out what brand horseradish the casinos use (we commonly stay at Bellagio or Mirage) at their buffets and if we can purchase it somehow? It would be an ideal gift idea for most of my family at Xmas time.

I'm a huge fan of your site and I was hoping you could answer a question. Are there any all-inclusive hotels/resorts in Vegas?

We are going to Vegas and my husband isn't a big casino person. Someone told him there is a Carroll Shelby Mustang Museum. Where is it located and is it easy to get to?

My wife is a crab-leg-crazed person. We are going to Vegas for our 18th anniversary and would like to know where the best seafood buffet in town is.

On the National Geographic Channel, I was watching a program called "Vegas Mafia." I saw some old footage of Frank Rosenthal with Oscar Goodman as his lawyer and in the background was a man who looked a lot like a very young Sen. Harry Reid. Was that him and if so, what was his connection to the case or the Mafia?
