Thanks for the help so far... some clarifications:
- If I do 40k in London for the Park Lane, I will still have 150,000 points to use elsewhere
- This is my 3rd time to London
- This is my 2nd time to Berlin - I am going back to germany to spend time with some friends and try out my new german language education

- 6 nights at the IC Berlin would be 144,000 points - would basically use up all my points - is that the best usage?
thanks - keep the suggestions coming!
