May sound a bit bizaar, but hear me out.
Following the success of the Iceland and Prague meets I attended a couple of years ago, and the Kiev/Chernobyl meets I couldn't get to (plus the others I've forgot to mention), how about this trip for the more adventurous amonst us?
Me, Ray (Iceland, Prague, LHR meets) and a couple of other non-A.Net mates are planning a trek to Everest Base Camp next year (possibly Spring, but could be Autumn). The trip is with a specialist holiday company that one of the party has travelled with before and can vouch for the quality of service (guides, etc.).
The trip is a trek, and whereas no special skills are required (climbing, etc.), it is a long trek (16 days), therefore one needs to be reasonably fit, particularly with regards endurance and stamina. But it is within the capabilities of most able-bodied persons.
The entire trip London-London is 21 days. Quite a long time to get out of work, I agree, but the price is the best bit. £1349 for the Spring trip (£1749 for Autumn).
Of course, trekking is not everyone's cup of tea, so make your own arrangements and make it a Kathmandu/Lukla meet!
Rather than cut and paste the info from the travel companies website, I'll post the link. For those with even the tiniest interest, be sure to click on all the tabs along the top!

And for the aviation nuts in us all, when are you likely to fly Yeti Airlines to Lukla?
