Contrary to many on here, we’ve visited Vegas a few times and enjoy it.
Yes, its very commercial and can if you’re not careful be very expensive.
But, we fly in, generally on a direct flight from the UK, spend a couple of days in a very nice hotel, rest, swim, find some good food, look but don’t buy from some very up market shops, watch people loose their money gambling but never never partake ourselves.
Once rested for 48 hrs we hire a car and clear off. Toured over the years California, Utah, Arizona etc etc. all of which are easily accessible from Vegas.
It depends what you want from the town, why go if you are not going to enjoy it?
