Which European holiday park/village has the best pools?

[ihatethecold]

My kids 10 and 13 just want to swim on holiday.

Have been to norcenni girosole and liked it.

Don't mind which country but would prefer near to the seaside.

Any recommendations please ?

Duinrell in The Netherlands has a huge waterpark on site, with slides, chutes and all sorts. It also has a small theme park.

It's about 3 hours from Calais, and my DCs loved it.

I came on to say Duinrell too! The first choice Splash resorts are good but £££ and the actual hotel parts a bit hit and miss.

Thanks, never been to holland.

Any more ideas?
