We travel as a couple and it's not always smooth sailing. The same goes for traveling with your family. Sometimes you get mad at each other. Sometimes you are crabby and snappy and sometimes things just don't go as planned.
How can you be around each other 24/7 without wanting to murder each other on a one- or two-week vacation? It's not always easy, but with a little planning you can minimize ruffled feathers and maximize quality time on your trip.
My number one rule is to make sure you eat when you're hungry. If you don't and your partner is notorious for getting hangry (angry when hungry) as I am, then everyday is going to end up with snappish or yelled "conversations". Find somewhere to eat when one of you is hungry or pack snacks in your bag for those times between meals or when you have to wait a little longer than you want to eat. I can't even tell you how many mean things pour out of my mouth when I get too hungry, and snacks will only last so long before a real meal is needed. Luckily, Eric knows it and will quickly steer me into a food place even if he's not hungry. Eating a balanced diet when you travel can help you feel better and less stressed as well.
Compromise your travel styles
No one is the same, which is good, because that would make the world a very boring place. Unfortunately, this probably means you and your spouse don't travel exactly the same. Understand your differences and understand what the other wants. Meet in the middle when things differ and you'll enjoy your trip a lot more if you're not butting heads at every turn.
Take some alone time
I understand that you are on vacation together. I do, but if you don't take some time to just go off and do your own thing, you will start to stress out and hate the other person's face before long. This doesn't mean that you have to spend a whole day all alone. Maybe go do a little shopping or even just make time to have your own space. We often have a vacation rental and will just go into different rooms for a while each day or he'll go swimming while I just lay on the couch and watch the news or a cartoon. Even 30 minutes of privacy can be helpful.
Do something you don't want to do
You aren't always going to want to do the same stuff. That's life. But this vacation is both of yours, so if you don't want to do all the same things, make a promise to do something the other wants and vice versa. You might find you have fun, but if nothing else, you'll know you made each other happy and that goes a long way, especially when you at least act like you are enjoying yourself. (If you don't, it really doesn't count as being nice.) Just remember, if your significant other refused to do the one thing you wanted to do most at your destination, you'd be pretty pissed, so keep that in mind when you're doing the thing they truly want to do.
Get enough sleep
Sleep is important, and when you don't get enough of it, it's like operating on only partial power. This is going to make you moody, crabby and probably mean. Make sure you get enough winks in, so you aren't close to snapping at any moment. It's better to miss out on something than to not enjoy doing it because you didn't sleep enough and hate everything.
If you don't talk to each other, then it's inevitable that something will cause an unnecessary fight between you. If you have questions about something or aren't sure how to get somewhere, communicate it. If you aren't having a good time, let them know. Maybe just voicing it will make things just a little bit better. Also, you can't fix something if you don't know there's a problem.
Be open to change
I can't even tell you how many times things didn't work out as planned on our trips. Nothing is going to go smoothly 100% of the time. Expect and accept things may change/go wrong/come up and be willing to adapt and roll with it. It'll all work out in the end.
If you can just learn to be a little flexible and selfless, then you can have much better vacations that are filled with fun and excitement instead of stress and crying. Not everyone is going to travel well together, but it can really test the limits of your relationship(s) sometimes. If you can get through a whole trip without tears or sniping, I consider that a success, but it almost never happens over the course of two weeks, I'll take the little victories.
