Most people who live in the UK or other countries recommend that one should rent a car from an agency in that country because of the insurance issues. Also- when looking at a rate- be sure it includes all the taxes and fees- not just the base rate. It can add more than 1/3 of the cost of a car.

From Hoover Dam you can get to Lake Mead which has a nice, relaxing and educational paddleboat cruise and Valley of Fire. VOF is simply stunning. The sandstone formations are out of this world. It is certainly worth the trip there.

thanks guys...

if anyone from the uk has rented a car in vegas who could give some advice on insurence, taxes etc id appreciate it:)

valley of fire sounds like a plan, depends on how much messing around itll be renting a car with being from uk though.

There's no "messing around" when renting if you're a UK resident. As vp03 said the best deals are to be had if you book and pay in advance before your trip.

Perhaps post again with "UK" in the title so that the correct people will read it and offer advice on which companies are best.
