Just go on your own, you'll meet up with other people soon enough.

I went to Nepal on my own... that was a bit of a spin, coming from early spring in Aus and turning up in Kathmandu in the middle of the wet season. But soon enough I was sitting in a roof garden, atop a 5 storey guesthouse with a couple from Austria, an Iranian guy who lived in Canada and a couple of Spanish guys, rolling up some of Nepal's famous black squidgy. Had a wonderful holiday.

As a certain footwear brand have long said ----- > just do it!
