Hiya,
Yeah I went with just you for the first time last year - to Peru - it was absolutely fabulous. So I'm going again in July. My original choice was in fact Vietnam, but that was cancelled, so this is my second choice, but it's somewhere I haven't been, although I've heard many positive reports.
Hope to see you at Heathrow! What area would you be travelling from?
Cheers
Anita
