Stuck for ideas for a room well HabboHotelFm has come to the rescue. Here are some ideas of rooms.

Cola/Mocha/Ice-cream Theft
Mocha theft is presumed to be started by merf,
but now many different versions of this game have been made. The aim of the game is to grab the mocha/cola/ice-cream, and sit back down again without being caught by the guards. The course mostly the same, but some adventurous Habbos have played around with it there has even been a v9 made. .
Work Of Art
Make a room that all the Habbos in the hotel will admire.
For example the throne pyramid a sign of richness, and great stacking skills. But you don't have to be the richest Habbo ever to make a work of art, some have done it with z shelf's and cactus's.

A Help Desk
Feel like helping other Habbo's and giving them tips and advice? Then make at help desk with help full staff.
The best help desk's have rares, to show that the owner has a lot of experience on habbo. But the main aim for a help desk is, give a warm welcome and help habbo's as much as possible.

A Salon
Tired of seeing Habbos with bad hair styles, well why not open a hair salon. You can make very small ones with just one facility, or giant parlours with loads of facility's.
You could even make a full beauty salon instead of just hair, if you really adventurous.

A School
Habbos always need a school so why not
make one for all the habbos in the hotel.
Allot of the big school owners have started
with one or two classrooms then got others to
add there classroom so eventually it turns
into a big school.
