Ds2 has his birthday next week- he absolutely loves swimming and generally fooling about in water so would like to find a good water park/beach. \n\nWe are Birmingham so a bit limited!! Anyone been to the SplashLandings place at Alton Towers? Looks like it may fit the bill but no idea if it will be truly horrid in summer hols? \n\nOr Cotswold Water Park? Looks fun if outdoors so obv rubbish if weather is? \n\nAny recommendations?
