I remeber HabboH, though it didn't ever average more than 150+ users. I believe it was running around when R59-R61 was the popular revisions. It was definitely a top 5 hotel.
It was the original, the first. His creation... also it averaged an usercount of about 40-50+ and peaked 105+ users after a merge with Yabbo.org (Turkish Hotel). Do some research and get back too me lad.
I checked it out, nothing too special. You need to figure out a way to get people to want to join your hotel. There's 500 other hotels who provide the same exact thing your hotel provides.
It'll be rather very difficult to get your usercount back if you're using a name like "Wubbo". There's been too many hotels by the name since the R57 days. In my own valued opinion, I'd recommend using a fresh new name. Something unique.
I've been playing Habbo & Habbo retros since the famous/well-known Version 26 (v26) was being used. I was introduced to retros around 2007-2009 (I can't quite remember), but retros were making big numbers. Take some of these retros for example, Habplus (managed to hit 2000+ users at one point)...
R63 is out of date, I suggest you move on the the R63B - doesn't need to be the version with the latest crypto but atleast consider moving to Plus Emu r1 and find a legit emu developer to help you stabilize it and fix the bugs. :D
