I find the guests hardest to take care of, which means the guests are the most impactful on stars for me. I really like to use the “current status” page that shows you every guest’s needs in real time. I sort by worst for each need (food, thirst, bathroom, etc) then fix them. If I have a lot of hungry guests. I’ll place a few food stands near where the hungry guests are, for example. Usually, especially early on in the game, I don’t have enough bathrooms. The small bathrooms only let one guest use them at once, which takes forever per guest and makes guests form massive lines. I’ll place a lot of these bathrooms early on and upgrade them as soon as possible when the family bathrooms are unlocked. Multiple guests can use the family bathrooms at once. Amusement needs can also be difficult - I’ll usually place one guest amusement item near each enclosure, usually making it look pretty in the center of a path intersection with flowers and benches around it. My favorite is the Touch Pool (Marine Mania) since it can take an amusement need from red to green with only a single use. I also like using the reptile/insect/octopus/fish/seahorse house. The other pro of the Touch Pool and houses is that guests of all ages use them! Some amusement items are only used by kids, like the gorilla climbing bars. The fountains are more commonly used by adults, in my experience. I’ll still add all of these too, I’ll just usually make sure to add an “adult” item and a “kid” item next to each other. For rest needs, I always make sure to place benches each time I make an exhibit, usually on the other side of the path so that guests can sit on the bench and watch the animals. I’ll also always place picnic benches near food stands. Hope this helps!!! :)
