Because you probably have limited opportunity to get out people tend to think to fit as much into outing as possible. A more important focus is to have a successful outing. you can always make future plans, however long that might take before you head out again. If you try to do too many different things and have too many new experiences, there's a greater chance of failure. Which could lead to setbacks and possibly decisions that going out is not for you.
Keep it simple and have a good time.
