Check in is a pain. We have to download a sonder app and then verify identity there by clicking selfies and giving a picture of identity card.
Parking is a pain too (especially if there is a game in the arena) the parking instructions were not at all clear and I ended up paying $40 a night.
If you check in late then there is practically no support. The extra couch bed did not have a comforter and my brother had to sleep in cold.
The support takes you to a hotline with British accented people who are in a different time zone. So all you requests take a day.
