We went there with the express deal last year. its got a child friendly swim pool (chute suitable for about age 5 up i should think, lifeguards a bit whistle happy, but friendly), soft play area with seating for parents nearby, bits for toddlers and older ones, great fun, also roller skating and dry ski slope (activities there for kids about 4+). Nice cafe/restaurant (its a costa coffee one) bar area is a bit smoky. They do kids groups free for an hour each morning in the bar area for each different age range (parents have to stay for the youngest group)i.e. music/toys/art.
The lodges are quite nice, they come in bronze silver and gold standard - we were told we could get anything from a bronze one bedroom (sofa pulls out to accommodate the other two people - i presume the sun offer is also for 4 people?) upwards, we actually were really lucky and got a three bedroom silver one, so the dd's had a twin bedroom each - i think it would have been tricky with just one bedroom tho. The bedrooms were quite spacios, the kitchen had most things. Some other people i chatted to there were really disappointed with it because they had no car and its a bit out of town, but i think they were a bit grumpy anyway. any particular questions? we thought it was quite good for the price. there's a lovely childrens farm to visit 8 miles from weymouth at abbotsbury (near the swannery)
