I'm celebrating my 21st birthday in AC on July 18-19 (Monday into Tuesday). I plan on barhopping in the Tropicana. Any suggestions on a hotel / tower / room type? I want to stay on the boardwalk. And I may be having extra people in my room so I want a hotel without security checking for room keys at the hotel elevator. I've read about this in people's reviews but I can't tell if this is done all the time or only on the weekends.
