You’re going on a cross-country trip. Airplane, train, bus, car, or bike?
The only way I prefer to travel is by airplane.
It gets you to your destination quickly and effectively.
Most train rides are more expensive and take days to get to a destination that in an airplane would take you a couple of hours.
You can save money that way.
There are also airlines that you can pay for the year and have unlimited flights which makes sense.
In a vehicle, you must be boxed in for hours it becomes uncomfortable, and bathroom breaks can be a hassle.
Traveling should be fun.
Make your vacation worthwhile no matter what you do!
