How long a wait for Sam's Grotto and The Edison after park close?

We are a group of 4 adults and considering a stop at a lounge for a nightcap after park close. Two we are interested in would be seeing the entertainment at The Edison on Saturday May 12, and having a drink at Sam’s Grotto on Monday May 14. But I’m wondering how crowded they would be and what the expected wait times would be. In both cases we would be arriving around 10PM. (Obviously we are not planning on RD this trip, lol. )

The Edison was not especially overcrowded on my visit back in January but it had only just opened. Know that after 10 there is a cover to enter there.

Cannot speak to Trader Sams. But going to find out in just 6 days!!!
