It 's been two weeks since I left for Costa Rica , although so much has happened in that amount of time that it feels like months have passed . For starters , getting to Costa Rica was a story in itself . I had figured out that it would be cheaper to fly to Costa Rica from Houston than from DC , and I wanted to fly back into Houston on the way home to spend a couple of days there with Lu .

Generate a question about the above context.
What may happen after they leave Costa Rica ?

[3]. They will visit their friend in Houston .
[4]. They will have a nonstop flight to DC .
