We were at WC for dinner a few weeks ago, April 14th, we waited about 10-15 minutes for our reservation. Then dinner took a little while because it's more of an event there with all the yelling and running around. We used the restroom and waited about 15 minutes for a bus which is down a path to the left as you exit the lobby. I don't remember the exact time but I think we ended up getting back to MK about 1 hour and 50 minutes after we sat down to dinner. I'm guessing the direct boat trip would be best but I'm not sure how frequently they run. Otherwise, bus to MK then monorail to CR would definitely take some time. So...the very unlikely best case scenario is you will get back in time if Wishes is at 10pm. It is more likely that you will not make it back in time. This is only my opinion and maybe some serious experts here could offer their opinion. I hope it works out for you!
