Paul, we haven't stayed at Hoburn sites but there are two other site in the Paignton area which I can thoroughly recommend, it all depends on the ages of your children and whether you prefer an all singing all dancing site or a quiet more relaxed site.
For a site with fantastic facilities for all members of the family whether wet or fine I would recommend Beverly Park at Goodrington ( approx. 1 mile outside Paignton and close to the beach and steam train to Dartmouth. This site is expensive but cannot be faulted for the amenities on offer.
The other site is a quiet family run site with outdoor heated swimming pool, small bar area with limited children's entertainment, shop and takeaway, there is also aa small games room on the site. This site is Widend Caravan site at Marlden again just outside Paignton. This site is quiet compared to Hoburn and Beverly Park but is far cheaper. Very clean facilities and a friendly run site with family only clientel.
As I say it all depends on what type of site you are looking for. Good luck and enjoy your stay in Paignton, we visit this area a few times a year and each time enjoy ourselves.
