I have been to E2Max to rent Guitar Hero on Wii to play together with my friends.

We booked the set for about an hour, (which was quite short since there was 3 of us playing and we only had 2 guitar sets. So we had to take turns playing). in the open arena. It's in a kind of cage and people could see us playing when they walk past, but I find the space quite alright.

They have 2 sets (1 set consist of 2 guitars for rock band) available for rent at the site, so if the set is already booked, you'll probably have to wait for another time slot or book it earlier (not sure whether you could do that though since we tried calling beforehand but nobody picked up the call).

It would be good if they also have the drum set for rental or have more sets guitar hero sets for rental.

Actually there are quite alot of games selection for rental, but I've not personally tried it yet. Besides, they also have LAN gaming area and you could also book a room with your friends to watch a movie or play video or boardgames together, which is quite a good place for chilling out.
