Luxury Hotel for short family break ?

[jackal]

hi chaps, thinking of getting out to somewhere relatively close to london for 3 nights in that dead zone after new years day

I'm after somewhere fairly luxurious with nice grounds, good food and a great indoor swimming pool for the kids (must be a child friendly place, ages 8 & 13) but don't really want anywhere too formal

thoughts so far:

the Grove: looks nice but looking for something a bit more special perhaps
Chewton Glen: too toppy really at ~4k for a 3 day break
Lucknam Park: not too bad pricewise and looks really nice


any other offers ?

hav also ruled out the 4 seasons in hampshire as weve been there before and want somewhere different
