'Museum of World Records' doubles the number of guests... Double?! Build 2 commercial buildings next to it. (Wedding and Steak house. I made a mistake.) In Level 11, lots without modifiers are counted as lots with negative modifiers. WHAT?! I had Big Neon Statue Upgrade, so it was no problem. Construction Mill decreases the amount of money to hire workers and buy materials. But this building decreases the income of 2 nearby hotels by 20%. (This disadvantage can be removed by Recycling upgrade)
