Guests from the future

Exploration Stage: Monster Hotel
From: Max O'Phobia
Description: I came here looking for a cure. I didn't mean to ruin the party... please forget it. My name is Max. I can prove it. I'm sure I have some identification somewhere, but damn it, where is it?
Completed: Thanks for finding my Entertainer ID. I must have dropped it in the confusion earlier. I'm still trying to figure out what era you guys are from, but I'm from the second half of the 20th century.
