I am not going to post individual car rental places here as you all know cars can be rented at the airport which you can rent prior to your trip and then just pick it up at the airport, they have several rental companies.

One tip I did hear about is if you rent through Costco on a Tuesday, you can usually get a much better deal.

Also, many Visa cards have car rental insurance so if you pay with a Visa card, check your policy and see if it covers this insurance, if so, no need to buy additional insurance coverage at the rental place. This happened to me and Visa paid everything even the deductible.
