You expected the trip to be fun together, but you are both exhausted from the first day. One person wants to follow the plan, and the other wants to decide as they go. What clashes is not taste but the way each of them makes decisions.
They have to make far more decisions than usual. Where to go, when to eat, and how much to spend all have to be decided several times a day, and each time, their ways of deciding clash.
Another reason is that there is no time alone. At home, each person can go back to what they were doing, but on a trip they are together the whole time, so even small discomforts continue without a break.
The person who made the plan feels their preparation was wasted. They spent time researching, and when the plan keeps changing, they feel that time has been ignored.
The person who wants to decide on the day feels they came to relax but have to follow a timetable. If moving to a fixed schedule is no different from going to work, they see no point in having come on the trip.
They make decisions at different times. People who need things decided in advance find it hard to bear an undecided situation, and people who decide based on the situation feel restricted when everything is fixed ahead of time.
They also want different things from a trip. When someone who wants to see everything and someone who wants to do nothing and rest go to the same place, their ideal days are complete opposites.
Dividing the time works better than compromising on everything. If the morning follows the plan and the afternoon is decided on the day, both people get what they want. Compromising all day long leaves neither of them satisfied.
Plan time apart from the start. Spending half a day separately and meeting in the evening is not a sign of a bad relationship. It is a way to enjoy the trip to the end.
They start avoiding trips together. If every trip ends in an argument, neither suggests going next time, and they end up with fewer memories together.
Arguments on trips are remembered for a long time. Words said when neither could get away from the other are hard to forget, and they come up again in later arguments about other things.
What a trip reveals is not taste but the way each person makes decisions. Taste can be adjusted, but decision styles clash several times a day, so it is better to know about them before leaving.
Once both people finish the assessment, the relationship analysis shows the points where the two differ. If someone who likes to plan ahead is paired with someone who decides in the moment, that difference appears, so they can talk before the trip about how detailed the schedule should be.
