Hey, I'm booking my honeymoon to DaNang, Vietnam and looking for an affordable way to go business class and with a nice hotel (not sure if this should be broken up into 2 different questions). I have a majority of my miles on Delta, but not enough to book their ticket and although Korean Air is part of the SkyTeam, its tough to find cross booking. Would it be better to try to earn miles through credit cards and shoot for an upgrade on an Asian airline or try to work through Delta as my main source? Also, in looking for hotel rooms, I am Diamond with Hilton and Platinum with Priority Club, but the resort I am looking at in Vietnam is the IC Danang Sun Peninsula. I don't believe that IHG status works at IC hotels, so would paying for Ambassador be worthwhile on a 7 day trip? Any help would be much appreciated. Thanks.
