After DLing and running the park as I looked the place over, I noticed that the peeps weren't as plentiful as expected. I got curious as to what the peeps were doing. So I clicked the peep tab and used the group "thoughts" feature. Sadly, at that time I found over 90 peeps wanted to go home. At the time, there was 580 peeps in the park. So that works out to roughly 1/6 of the peeps that wanted to split. So I hope you don't take this the wrong way. Because I'm about to dump a whole lot of observations and suggestions into your lap.
I did a little more looking around, and discovered that there was a rather large imbalance between flat rides and coasters. I also discovered that there was only a few food courts (like about 8, but they didn't offer anything close a diverse selection of fare,) three information kiosks, (two of which were right next to each other,) and only one first aid station. Bathrooms were paired, mostly, and there wasn't enough of a dispersement throughout the park as would be expected.
If height is a problem, consider lowering the food court just one level lower than the surrounding ground level. You can't build a wall on the tile that a booth sits upon anyway, so slope that vacant tile to a lower level and you can place taller food stalls within the structures.
OR, you can try my trick, put the food courts underground. And enclose the ramp to the underground with a smaller themed structure. Using two stairway sections, then flatten out so that it's deep enough for restrooms. Then go two more stairways deeper, and you can build practically any food stall you want. With a little experimentation, you can create some pretty ornate food court layouts. This not only removes the food stalls from the surface, but opens the area up for more rides and coasters.
I also noticed that you have some good sized structures that are, for the most part, empty. So what I suggest is this, create more food courts IN those mostly empty structures. Put a restroom AND a first aid station along each coaster exit, that has a nausea rating of medium or higher. Make sure that you place the No Entry sign between the exit and the restroom/first aid station. Or peeps can't access the restroom from the midway.
Another idea, combine those larger coaster station structures with a food court, so the structures can pull double duty. Provide a footpath from the midway to the food court within the structure. And DON'T lead the exit of the coaster to the footpath of the food court. That'll spew it up for sure. That's taking advantage of the space provided, rather than let the empty space go unused. As for the extra spew generated? It's nothing an extra handyman can't control. So assign a handyman to just the food court, and overlap handyman coverage areas slightly in areas that generate a lot of spew.
There are long stretches of footpath that are, for the most part, boring. (Not to mention that a lot of the footpaths are 4 tiles wide. Which makes it super easy for peeps to get lost, as they'll simply walk in 4x4 circles.) Real parks are nothing like this. They're full of flat rides of all types to satisfy everyone. A park does not live by it's coasters alone. Even if the park has some remarkably nice ones, like this park does. (I would compare it to Cedar Point) but it needs to diversify. Otherwise, the peeps will walk out the gate.
As far as landscaping is concerned, it looks pretty barren. I would definatly spend a park building session in order to place gardens along the footpaths, trees benches, lamp posts, trash bins, etc. along with other ornamental plantings. You'll be surprised how this effects the peeps and they'll be more likely to hang around and spend their money.
There needs to be some contrast to the flat land. Like some hills, even a desert has some dunes. And some paths that are multi-level as they route the guests over, around and through some of the hills. Having just flat land, is, for the most part, boring. Check out some of the best parks at NE. You'll be hard pressed to find one built on strictly flat landscape. An undulating landscape is also more challenging to create coasters upon. Definatly more exciting, and that'll keep the peeps interested in the park. Most people will build a coaster THEN pull the land up around it. If that offers you any hints.
I hope my suggestions do you some good here. I wouldn't think that you would have to use them all, but any of them are going to go far to improve the park as far as the peeps are concerned. Oh, one more thing... I'd definatly move that real gate to where the gate structure is. It's sort of lost in the corner where it's at. You may even want to place two gates side by side. As this will probably fit the design of the front entrance area better anyway.
But in a good thing. Lots of tips were suggested.
