Have you thought of taking a solo flight and then meeting people as you go? I know the idea of going alone can be freaky but if you stay in hostels you will meet people in no time?
I travel solo all the time and have eventually got over the paranoia of being alone (though I'm actually rarely alone!). I have a list of hostels in Asia (and Latin America) on my blog where I've always met great people: www.indianajo.com and have some tips on solo travel.
Not sure where you are, but Easten Europe would be both cheap and warm in July...I'm in Asia at the mo and it's heading into rainy season (hot and cloudy) but, as my grandmother used to say - you're not made of sugar!
Hope you find what you're looking for - may the road rise up to meet you
