I've done that one too, cca 7 years ago. A bit harder variant - 3 passes trek, where EBC is a side hike. Amazing place and whole region too, can't get enough of that country. Other valleys are much more remote seeing only fraction of the main EBC route traffic.

If you are not part of organized group (I went solo), without prior booking it may be tricky to find accommodation in Gorak Shep, sort of bottleneck since everybody goes to EBC for morning views on the top of the world and its the closest place. I ended up convincing one of owners of guest house there to let me sleep with them in dining room, it was -10C outside and my sleeping bag would not be up to that, even in dining room it was just above freezing.

Wishing you good weather for nice views from Kala Patthar and on Ama Dablam!
