Indonesia/Thailand/Costa Rica/Sri Lanka honeymoon, thoughts?

Hi everyone,

My fiancé and I are planning our honeymoon for next year. We are pretty flexible on the time of the year we can leave to optimise best weather where we'd go. Our idea is to do 2 weeks: 1 week in a beachfront quiet luxury hotel (more relaxed, nautical activities) and 1 week with a bit more of a cultural angle, or to see another type of landscape scenery (tropical forest, jungle, temples etc.) – Have any of you been to one of these four countries? Which would you recommend?

Thanks!!
