Actually VPS is the pro and portforwarding is the cons in one hotel.
VPS is actually a lot better for Habbo emulation rather than portforwarding a personal computer. Portforwarding will mostly lead you in getting hacked unlike in a VPS wherein you choose only what is to portforward and that you get support from the hosting you purchased it from, which means -- you'll get less trouble and a lot easier to use a VPS rather than a personal computer. And that you will not pay for electricity bills but for the VPS instead. There are also special features a VPS has that is so appropriate for a Habbo Hotel emulation.
