We have been to Bonita Lakes RV Resort http://www.bonitalake.com/
several times and to Lake San Marino only once, and once was enough.
Their utilities are very good, all connections are in the back. Wi-Fi for a RV park is good and the hosts are great people. Also you can actually have a water view (some sites not all) of a canal with a lot of ducks. Streets are narrow, but are one way, so that has never been a problem. The park is also a lot quieter than Lake San Marino. Bonita Lakes is on Old US-41 and it's easy to get in and out of the park.
Lake San Marino
: They say they have Wi-Fi, but they have Tango Net, and it does not work. They said they have a "hot spot" in the club house. The time we were there along with several other people none of us could get it to work. Their streets are also narrow, but they are two way. Most of the residents are very impatient French Canadian and do not like to wait while you back in. It does take quite a few turns to get into a site because of the narrow streets and narrow sites. You are very close to your neighbor here. They say they have a lake view, well they do if you happen to have one of the permanents on the lake, otherwise no! Also they have very few 50 Amp sites, mostly 30 Amp. Sites are very close together, lot closer than Bonita Lakes. We had a reservation when we went and they couldn't find it, then we wanted a 50 amp site, which we specified on the reservation and we had to wait for someone to leave before we could have that site. They did find the reservation later. The hosts may be volunteers, not sure on that. If you are anywhere near the road going past the park, big trucks run back and forth starting about 4 to 5 AM every day all day. The road dead ends into a stone and concrete plant.
Price wise, both are about the same. Also, both are back in only. And by the way, these parks are only about 3 miles or so apart, so you are close to everything.
They above is just my wife and my opinions, in the end you have to decide for yourself. Read the reviews on RV Park Reviews :: Campground Search
