Needs to be in the UK, central-ish as the 7 of us are strewn across the country.
Nothing too wild, been there down that (can't take the pace/hangovers anymore!)
Center Parcs is a possibility because of spa.
Also thought about a health farm type thing...... definitely a spa needs to be involved and possibly shopping (realise CP doesn't do shopping but its an old favourite of ours)
TIA
