2 years ago I tried to fix a whole catalogue (read: Missing furni, adding top quality custom furni, animations, furni states, walktrough, sit and stackheight, ...).
Even tho people were advertising a lot for this hotel, the staff was decent, ddos protection, decent events and rewards, and we had our own CMS with quite a few features, people didn't seem to be bothered with the bad furni in their current hotels.
I must have spent at least 5 full days (do the maths, 24x5, not just a few hours every day) to get the catalogue in a somewhat decent state, just to close the hotel after 10ish months, because of the lack of users actually staying there.
