I've looked above but no one seems to have addressed my simple issue - virtually nothing makes my park rating go up. There are always 1-3 rides with big red exclamation marks that will make my rating drop and any ride without one usually has a 10% chance of a 2 point increase but at least a 20% chance of a rating drop instead. I have the girls maxed, have done all I can with the 4 villains at the pub, have gotten every advancement from the Dwarves, have over $800K in the bank, and I can't get a date with either girl because my rating is at 0. All I have ever seen to make it go up is to build a new ride (none available) or get lucky when I select a ride (statistically unlikely to help, see above).
Any guidance is appreciated as I cannot find any additional options to select to move things along.
