Selpol, I agree with Panda use up those extra segments in North America. Our home airport is DFW and we are on our second RTW. One of the tricks is to be sure that you go some where that the lodging and transport is plentiful and affordable.

We really enjoyed SAN i.e San Diego we stayed on Coronado Island - lodging is a bit pricey. But we really enjoyed the walk to the beach, the bus rides, affordable taxi to airport the view from the bridge over to the island are great, and the ferry ride. We did it Thanksgiving week all and all a good trip at a reasonable price.

We just changed a trip for this Christmas from PBI to SJO because the lodging prices look really good and will not need to rent a car (just makes for a bit more relaxing holiday trip).

Just a couple of examples. I am sure you can find something even more interesting to you, go for it!
