I thought the Do was awesome as it was, though I could definitely be up for a day or two more. Key issue for me would be whether it's possible to keep up the tempo/intensity of events for a longer tirip.

And other key is timing it between my inflexible biz trips, though not much I can do about that...

And hey *A -- partly due to the great experience and hospitality, I have a CO status match and am dumping Delta/Skyteam.
