we went to haggerston castle with dd1 who was 18 mths
it is almost the best holiday i have ever had!
i think we were v lucky with the weather tho - we were able to sit around the outdoor pool every day
the caravan we had was lovely - we went for a gold standard one, but we took our own sheets and pillow for dd1
we ate out once and it was v expensive - from there on we cooked in the caravan, but just bits and bobs, i made sure i wasnt chained to the kitchen!
we also made the mistake of using the on site shop - again v expensive, but after that for anything else we needed we went to safeway which was a 5 min drive away
the swimming pool was great for dd1, we also went on horses, trampolines, the boating pond, and at night time we would wander over to the main area after tea, they would have a little disco on for the children and we would sit at the outdoor bar chatting til about 8 or 9 pm then we would wander back with dd1, put her to bed and sit outside with another bottle of wine!
i fyou are going to haggerston there are lots of great places to visit closeby i could let you know about
there were some down points - the pricey restaurant and shop, the switchies and burger king which you had to pass to get to the main bit, but apart from that it was great!
