Stayed here little over a month with a brand new 2021 Jayco 284BHS.
Pros: Good location. Lots around for anything you might need. Super friendly staff. Small fenced-in dog area. Quiet accept for the train at night. Most sites are angled. Easy in and out. Nice concrete patio and gravel sites. Beautiful St. Augustine grass (watered nightly) Water, power and Sewer are all close together. (see picture)
Cons: Small sites with no furniture or fire pit. (no room anyway) The patios are higher than the gravel so you might have problems with fold out stairs. Train tracks are across the street but not terribly loud. Not louder than an AC fan. Larger rigs will have a hard time maneuvering in and out. Not much room to park a vehicle. Internet is hit and miss a lot of the time. Not reliable enough for work. Water pressure is sub-par. (see Pic) I changed my filter and still had issues.
Honorable mentions: Price is higher than average because of location but well worth it. Very little shade in a few spots but mostly very open. Nice you don't have to clean your roof off all the time.
Overall, I think it's one of the better locations in MIA. I would recommend a stay here to friends.
