This basic point has been repeated by multiple respondents because it is right on the money, at least in our experience. Right now you just don't know how your baby will adapt, and you don't really know how you will adapt either.The problem is that you don't know if you are going to have an easy baby like Obgraham's or one (like one of mine) who sucks every last bit of energy out of you, mind, body and spirit. An infant/baby/toddler who cries all day long and sleeps poorly can turn a "vacation" into a living hell due to lack of routine, disruption of sleep schedules and lack of familiar environment. Seriously. Wait until baby is born, and get to know their ways before committing to a trip such as you proposed.
When our first son was born, I was fortunate enough to be able to get six weeks off. We primarily stayed home and got the newly upside-down routine somewhat normalized. My wife was a superhero. We traveled a bit, and it was fine, but everything was more complicated and took a LOT longer. Maybe you could fit in climbing outings and Spanish lessons, but I laugh when I think of us trying that in those first months. If you do travel, I would urge keeping it simple and keeping expectations low. You can always adjust later depending on how Baby decides things should be.
I was reminded how tough it can be when I made some ill-advised remarks a few years ago to a wonderful sitter who had been working with us who was expecting her first child. When she asked how we had done the first few months, I said something to the effect of "well, it's a lot of work but unlike later, the baby sleeps a fair amount so you do have some time with each other and to get some things done. That changes later." She called me a few months later and said: "What in the world were you talking about? We're always exhausted!"
I think maybe I misremembered those early months because it did seem later that EVERY SINGLE FREE MOMENT was spent dealing with toddler issues and I thought "yeah, earlier it was a bit easier." Also I was speaking from the Dad's perspective. No matter how hard you work, the Mom always has it much harder. MUCH harder. Always.
So anyway, congratulations and best of luck on your new adventure! Sure, our kids drive us crazy sometimes but it's been a blast! I can hear one of them right now playing some sort of commando game with a sleepover buddy... The years go by quickly....
