The parking is bad. They have underground and surface parking. We normally find a spot and then don't move our vehicle again until we leave. The first time we stayed here, we didn't realize how bad it was and went somewhere, returning after 9 PM - we only found one spot, for a compact car (so, it totally wouldn't fit our extended-cab, full size pickup). We gave it to the valets, who parked it (no additional fee for this). They basically double-parked it in their backlot area. Before that first stay, I had inquired about bringing a second vehicle and they told me that they had an agreement with a nearby facility that we could park our second car at for $15/day. So, offsite is an option, but I think they normally just double-park in their restricted-access area for the valet.
That was the only time we've used the valet. Normally, we find a spot, park it and just keep it there.
