Oct/Nov holiday with 3yr old in France - recommendations?

[Abbaye]

Hi all,

We live in Brittany and want a weeks holiday at the end of October with our 3yr old son who is a bit of a livewire!  We thought Centreparcs would be good but its half term around then and full up practically so are looking at other options in France (not too fussed on flying at the moment).

Can anyone recommend somewhere with an indoor pool (ideally pool complex, water slides etc), beach not essential as if the weather is bad we wont be going to it, kids play area and perhaps kids club/creche, and nice restaurants for mum and dad.

We dont want to spend all day driving so either trainable from Rennes or drivable from us (Dol-de-Bretagne) in about 4 hours max.

Thanks.
