In reply to Burty21:
> Regarding the trek though, Mera is simply a walk at altitude. It is tough and hosts remarkable views, but isn't necessarily 'climbing' .
That's like saying playing a 'cello is simply pulling some horse hair across a string. It may be technically easy, but there's still the objective dangers that go with Alpinism.
I think being so dismissive about a mountain, especially to a relative novice, is dangerous.
OP: It's very doable - look, as has been suggested, for local companies in Kathmandu. We did Island and Mera (a good few years back) for about £1500 - £2000 a head, the majority self-organised (bar booking Sherpas / Sirdar).
I can recommend these guys:
