We have a mandatory shut down during July 4th weekend, and I would like to take a solo vacation. Traveling from sfo.

I would love to go to Europe, but July fares seems high, I'm quite flexible and can wait if there are fare sale that pops up. Don't really care which city to fly into.

I will be in Asia end of the year, so no Asia for me, and I don't want to go to Mexico, I enjoy a variety of things but I don't want this vacation to be just staying in a resort type.

I enjoyed Prague, Tokyo and bankok a lot.

Where would you recommend. And what strategies I can use for scoring a cheap eu ticket tha week?
