We park at Vista. Pretty sure it's $11/day with the internet coupon. Gated with 24 hour security. Valet parking, and shuttle by request.
We've used it several times now, and plan on using it again for our trip next month.
As a matter of fact, it appears to be across the street from the airport's LT parking (entry via the Howard Johnson driveway). But, we like the 24 hour security (the lot is fenced in and patrolled) and the fact that the shuttle is by request. They help you with your bags, etc. When you return, you call them as soon as you have your bags, and they tell you where to meet the shuttle. Never waited more than 5 minutes. Tell the truth, we probably wouldn't leave our car in the airport's LT parking, but that's just us. YMMV.
