I hate to tell you that you should've done some research but.... it is monsoon season in Tucson currently, and I would expect the deserts of Las Vegas to be hot in the middle of summer too. Las Vegas isn't going to be any hotter than I would expect at this time of year, low hundreds. You will be best off staying inside during the day (gamble, go shopping, chill out in a spa, look around inside the hotels, museums, star trek experience if you're desperate!) then explore the strip by night when it's cooler, looks far better, and the belagio fountains are on, don't forget the mirage volcano and treasure island show either. Outside in las vegas in the summer heat is just a dump, but at night it comes alive, unfortunately that's when a lot of people lock themselves in the bars/clubs/restaurants/casinos. Try to do all of that during the day instead, and do your sightseeing at night. Get well soon, and keep up the good work, both with the blogging and general ambulancing malarky.
