Things are going to be changing quick! Babies follow marriage. When they come, you'll really be anchored. So I would suggest you do things now you won't be able to do once the family starts growing. Like travel. This will take some research on your part and, unless you two are primadonna's and won't accept anything less than 5-stars and top-shelf, you'll find it's not as expensive as you thought. When I was younger, I did what all young people do, stayed in hostels. I stayed in the Generator in London. You write budgets. Perfect. Do your research and write a budget. Travel is a great way to escape your stuff and gain new experiences. If you stick to the big cities, you won't run into a language barrier because everyone speaks English. Think of yourself as a voyeur. You're only passing through a movie set completely anonymously.
