Hello!
This is Quirze, from Barcelona and this site looks really useful. I'm sure I'm gonna find a lot of tips and experienced people here ;)

We're planning a road trip through the western states (mainly california) with a friend and our partners (4 people in total) in August-September of 2012 during 15 days. The plan is:

San Francisco > Yosemite Nat. Park > Sequoia Forest > Death Valley > Las Vegas > Grand Canyon Nat. Park > Los Angeles > San Francisco

First of all, I would like to know your opinion about if it's better to hire an RV or car+hotel. I assume that there are several reasons to choose one option or the other: cost, agility of the vehicle, comfortability, better for sightseeing... so I would like to know your comments :) The plan isn't luxuryous hotels nor activities, we just want to admire those beautiful spots and landscapes

Another thing is, are there any reccomended car/rv rental companies?

Thank you all for your comments!!
