How important is vallet parking??

I went to my rh yesterday and had asked if they include vallet parking and he said no. They actually prefer no vallet parking. He could get us a company but they would charge in the thousands! He said that since we are the first party by an hour we will have all the parking right in front of the building and doors. Looking at it, its not that bad but I'm worried it won't go over too well with our guests.

Any opinions on this? We really don't wanna shell out that much money for parking of all things...
