Where should I fly in August?

Taking my first big vacation of residency with me and my girlfriend and planning it for August. Have about 200,000 miles that I was planning to use for flights. I would have about nine days.

Curious where people suggest I should go ?

I have been to Croatia, Italy, Ireland.

I was thinking London, Amsterdam or Honolulu right off the bat. Where have you travelled that you always wish you could go back?
