In late October 2016 I spent 10 nights at Sugarloaf Key/Key West KOA. Positives: All campground staff were very friendly, helpful, and hard workers for their customers. They made you feel welcomed. This was the 7th campground I stayed in during the last 2 months and KOA Sugarloaf was my second favorite.
I paid for internet as anticipated… the Nomad site was fast with no interruptions… Yahoo!!!
Not so positives: My campsite was quite small, no cement or grass, but very clean and level. Cable was free but reception was very poor. I could not view the sunrise, sunset, or the big open water from the campground nor was my $90+/night beachfront campsite private. The beach is shared with the whole campground so at times my space was invaded. It was quite busy and noisy with people cutting through my site. Was this my misunderstanding of a beachfront campsite?
The campground is located right by US 1 so the traffic was heavy and noisy throughout the night. Would I return? Absolutely. I just would not pay for a beachfront site but rather a less expensive one tucked within the quieter, more private spaces of the campground.
