Where Should I Go?

I have a task for you all…

I have some annual leave at the start of October (1st-11th), and I am looking to go away somewhere, but I need some ideas for possible place/s to go.

Budget is £250-300, and this has got to cover flights and accomodation, so it will obviously have to be somewhere in Europe as I doubt I would be able to get anywhere further than that.

Also, I would prefer it if flights were on a Star Alliance carrier departing to/from LHR as I live very close by, but LGW would be fine as well.

Any suggestions, please post below.:)
