DP has said for years that we should go somewhere warm for Christmas to give MIL a break, as she always hosts (no one else has a house big enough!) and she'd like a Christmas where she can relax and someone else cooks. However, it needs to keep everyone in the family happy and not be £££, are we asking the impossible?!
We have:
PIL - mid 70s, various health issues including FIL's mobility, they are fine on short flights (Canary Islands etc) but wouldn't want to go much further afield - like to spend hols pottering about or relaxing at the hotel
DC - twins aged almost 8, very active, like to do lots of exercise
DP - doesn't mind doing a bit of sightseeing but frankly would prefer to spend all the holiday doing zero
Me - bound to end up knackered anyway as I try to accommodate everyone 
Really what we need is somewhere half board/ full board/ all inclusive, reasonably warm over Christmas, with plenty of activities for the DC but also no hassle for PIL if they just want to take it easy.
Am I being a bit optimistic thinking we can find somewhere to suit us all that isn't megabucks?! We looked at Tenerife as FIL really likes it there, but it was coming out at over £2K per person for around 10 days, which isn't really doable
- any suggestions gratefully received!
