General R63B Help

I've been running R63 Hotels and want to completely drop it and make an IIS R63B from scratch.

I have no problem setting up a hotel, but was wondering if there is anything I need to know about R63B that might cause issues.

What's the best EMU?
(Willing to pay for stable EMU)
Best CMS compatible?
Any known issues?
Really anything you wish you knew before going R63B.

Thanks in advance,

Best R63B Emulator is Azure for now.
There are updates every day by a small team of devs.
We will release stable builds every 2 weeks with new fixes etc.

Best CMS for beginners is revcms in my opinion but if you want to use the exact same one like Habbo.com now, use azureweb. :)

Thanks I appreciate it! :)
