For Christmas my son's girlfriend has given me a voucher for a spa day at a very posh hotel. I'm really thrilled with such a lovely and thoughtful pressie but also a bit anxious -I'm not a very posh person. I'm overweight with lots of wobbly bits and think I may feel a bit intimidated by it all, but I know this probably cost a lot and wouldn't want to waste it. Has anyone done anything similar and can give me some tips or reassurance? Thanks BB
