- I reserved 3 spots for a company Christmas party. This was convenient to have it paid in advance. The only thing I would suggest, is to put instructions on the printed ticket that you have to press the help button for assistance. If it was on there I missed it somehow. Even better, would be if you could enter your online code on a keypad with the reservation number. This would speed up the process greatly. Otherwise,this saved me way more money than parking at the Westin.
