I'm wondering if the one you are thinking of was the
Oceanic Campground in Shediac.
We stayed there a couple days last year with camper & tents.

Amazing park and great operators (who actually enforce the park and safety rules).
Not to mention the 'hotel like' bathrooms & facilities were awesome & the pool and playground were very, very nice as well - my kids had a blast!
Alot of seasonal trailers were already in place as it's a new park, and they were still adding some updates - they have seasonal lots, small serviced and unserviced lots.
We enjoy the Island View family campground in St.Andrews as well - clean and safe & lots of activities!
