We stayed here for three nights with our daughter, son-in-law and their one-year old and six year old. All in our 34' Bounder... 'nuff said. The park is very nice. The sites are well laid out with a good mix of seasonal and transient areas. Roadways are wide enough for even the biggest rigs to navigate. We saw several 5'ers that were huge even next to our motorhome. Bring your leveling jacks, though, as not all sites are perfectly level. Bathrooms, laundry and shower areas that we used were clean and well done. Camp store is well stocked, but typically expensive. Nice pool, two lakes, one for swimming, one for catch-and-release fishing. Couple or three playground areas. Activity room, etc, as described on their website. Lots of kids buzzing around on golf carts, but we didn't run across any delinquents. Overall, a nice place to stay, but make sure you have transportation; outside of the park, there's not much within walking or even bicycling distance.
We called TB RV park about 3pm on a Sunday, to see if they had any open spots. We were up the road at Delaware Seashore State Park, hoping for a cancellation. They didn't have any, but TB had a few spots open, so we grabbed one. Fenwick Island is just above the resort area of Ocean City, MD. This is a very 'touristy' place during the summer months, just down the road from Bethany Beach and Rehobeth Beach. There are few campgrounds along the beach area, Treasure Beach is about 2 miles west of Route 1 long the inshore bay area. We got here about 6PM. The first shock came when I un-holster'ed the Master card and the lady at the counter said, "Oh, we don't take credit cards." Perchance, there was an ATM right behind me. So rather than pay the couple percent to the credit card processor, they skim off 50 cents or so on the ATM fee. Nice racket, I suppose. Anyway, apart from that, the place is nice. A huge number of spots, but 90% are seasonal and long-term campers, so they have only about 20 or 25 transient sites. We got water and electric, didn't need sewer. The pool area was nice, as was the playground for our grand-daughter. Showers were free and reasonably clean. We didn't use the park store or any other facilities. There was a very nice breeze blowing in from the ocean, so we didn't even need the AC on in the MH. Sunday night was kind of quiet in the park. Our spot was a level, grassy site, no complaints from my POV. There were a large number of 5'ers and TT's in the park, as well as the almost-permanent looking trailers that had fenced in porches, gardens and storage sheds on their sites. The previous reviewer who mentioned the poor tenting area was right. This is not a place for tenting. Also, some of the corners between the lanes might be tight for a longer MH to navigate. But other than that, Treasure Beach was a nice enough spot.
