I guess I'd suggest trying to get a little shelf space in retail video game stores (target, GameStop, et cetera). Even if it's just enought for 4 or 5 games. Do some multi cart 2600 game packs to be add ons for 2600+ purchases. Later if we talk you into 130xe repos you can rotate through some classic games on carts too. The audience isn't as big but one exists. Just had a contractor notice my atari 800 and start asking about how he could get one / loved his as a kid... plus with fujinet you have wireless and with a big atr on the sd card a virtual hard drive... Pretty easy to use and desk isn't cluttered with accessories (disk drives) anymore.
As to the hotel; I'd be in just because there are few good arcades. Dave and Busters is all there is chain wise and they don't really have many good games. Like people go to casinos hotels just to gamble and have dinner (without staying) I could see some people doing something similar with a arcade hotel.
Last of all I think Atari has a window right now if they can take advantage of it. Modern gamers are complaining right now games look good but aren't actually fun to play. If you sell a system for the price of a AAA game and games for $8 instead of $80... Pointing out your games are actually fun..
some people might try Atari out.
