Indeed we did, no altitude sickness, though I did struggle with heaving breathing the last stretch, but made it all the way there and back.....sheez, some of the climbs on the way up, a 2 hour continuous uphill climb can be soul draining at times!
Amazing views, our weather was fantastic, sunny and clear skies every day....hardly had to use down jackets or even sleeping bags (some great thick duvets at the tea-houses), except occasionally at night. Its gets very expensive the higher you go, which we were expecting, but R65.00 for a 500ml coke is a tad wtf

Anyhow great experience, loved Nepal and the chaos of Kathmandu - we had a driver from the trekking company for Kathmandu, dude must have balls and nerves of steel.
