I like that it is easy to use for both employees as well customers/visitors in our facility! It has helped us track how many cars we have parked at different times throughout an entire day or week etc., so there are no problems with tracking this information ourselves anymore!! We also love being able be notified when someone leaves their car unattended which helps keep everyone safe by not leaving keys inside unlocked doors. There really isn't anything bad about using o valets system other than maybe some people don’t know what they need but once you get used too its great. !
