We've had dinner at Yak and Yeti after park close in 2016, one of our favorite memories. Walking through the park after everyone is gone is simply wonderful. We were able to go back to Port Orleans with a bus no problem. Enjoy it!
We had a park closing Oga's last year at HS. We waited a while to get in and didn't see any other people on our way out. It was actually really cool. Had no issues getting a bus to CR.
