Holiday within a reasonable drive of legoland

[LaDiDaDi]

We will be going on holiday at the end of August and dd would love to go to Legloand, we live in the north east so the ideal would be to travel south for holiday and then go to legoland for the day or weekend.

Any ideas on a nice holiday lodge park with a good pool for kids and other facilities within an hour or two's drive of legoland?

Centreparcs Longleat - too dear for use but does look great - alternatively house swap with us for free - approx 45 min drive to Legoland - 25 mins to PeppaPig World - we have a somewhat child-worn three bed semi.
Good Luck
