I don't know if you have already done this. But the most important thing is to discuss with your spouse/fiancee what the two of you want from the trip. Then plan accordingly. There is no right or wrong: each couple wants different things
Some people would like to just spend time together, some people would like to sightsee (monuments, nature) especially if it is the only chance they will get for the next few years; some people want experiences (adventure/cultural/culinary); some people get a thrill from a few days of luxury; some people don't mind eating street food with a loved one for company; some people just want to escape from the family for a few days; some just want to relax after the hectic wedding festivities. So talk to your SO and work out what the 2 of you want from the trip
