Hello, our family of 4 is trying to find a way to DPS on award travel, this summer mid June when school gets out, to mid July. Ideally it would include a stopover in ICN on our return for a few weeks - July to early Aug. I've looked up options but difficult to find. One thought was fly to Singapore and get separate tickets on low cost carrier into DPS and back? We are located DC Metro but open to flying out of any domestic City that could make this happen. Can anyone recommend a best carrier / flight option that could make this work?

Not sure if this is the correct forum to post this question.

Thanks for any advice!
