If you aren't having fun, it might be too easy. Make a challenge... say, you and your friends have to split up for X number of days and can only spend Y amount

If you aren't having fun, it might be too easy. Make a challenge... say, you and your friends have to split up for X number of days and can only spend Y amount of money in that time (it's an honor system kinda thing). Or, you could agree to race to a specific destination, but only travel in vehicles with two wheels, or no motors, or something like that.
