If you are flirting and you want to kiss or hug and the option isn't there get out of flirting then click it again there should be different options every time unless you ran out of options.

Have at least 3 entertainers 3 groundskeeper and 3 Mechanics to keep the place tip top. When making a roller coaster don't make so many twists and turns until you ride down a hill and get speed or it will be boring, remember it's not about having a lot of crashing, twists, and turns, It is about how fast you go while doing it.
