All the childrens' menus are the same in each restaurant (mostly organic) and have been balanced properly for small ones with fesh veg etc.
Things like shepherds pie, sausages and mashed potato, spag bol, salmon and cheese sauce etc. They also give free jars of organic baby food.
Once the kids are old enough not to turn purple after being in the pool (don't mean it's cold, just that babies and toddlers get cold quickly) we found that we could spend most of the time in and around the pool dome.
We did the phot thing too - 30.oo for sitting, one free 7 X 5 photo but the rest are really expensive (but you don't have to buy any others).
You oculd play table tennis/badminton with LO in pushchair (about 6.50 pp for badminton I think)and around £4 for ttennis.
Play areas good - crazy golf, you can take LO in pushchair.
Pedallos (around a fiver I think).
You must, must , must get DH/DP to have kids whilst you have a spa treatment at the Aqua Sana. It's so tranquil and lovely.
We only live 35 mins away at the moment - shame they only do day passes for guests already staying, otherwise I'd be there every weekend!!!
