I'm beginning to plan for me and my girl-friend's Xmas vacation.
We can leave December 25 or 26 and would need to be back by January 3.
We can start from basically anywhere in Europe and would like to go someplace warm (beach destination). Some culture/history would be nice, we're not that interested in going to Dubai, for example (and besides, it's not that warm in December).

Last year I bought discounted business-class tickets to Puerto Rico (about 1000 € per ticket).
But now we have collected some miles, so I'm thinking about redeeming them instead.

I have (rough estimates):
- 300k German Amex Membership Rewards points.
- 220k Avios
- 40k Aegean miles
- 50k AirBerlin Topbonus miles
- 70k SPG starpoints

Is there anything in particular you would recommend us to look for, which is good value or where it's likely that award space will open up?
We would like to fly business or first class.
Thanks!
