I'm in the middle of a RTW right now, and I'm at home. (Well, at work actually.)
In February, I flew from Boston (home) to Stockholm on the outbound leg of an award ticket. I started my RTW in ARN, and spent 17 days (10 vacation days, 1 company holiday, and 6 weekend days) traveling to Berlin, Bangkok, Lijiang, and Tokyo before returning to BOS.
In August, I'll take 2 weeks (incl 3 weekends) traveling to Paris and Kenya before returning to Stockholm to complete the RTW. Then, I'll use the back half of my award ticket to fly ARN-BOS.
It'd be nice to have more vacation, but that pesky job pays for the travel.
