Do you travel alone or with family?

All the time I travel alone. Why? Because nobody wants to go to my destination of choice or their passport won't allow them entry to my destinations.
Another reason is I usually don't plan my travels. I always play it by ear. I always travel when I feel ready to travel. I book my international flights 2-3 days prior. Many people aren't used to this kind of spontaneity -- they want to plan their trips months prior. I don't think I've ever planned my trip like that. I don't think I will ever plan my trips like that.
Travel also requires money and free time. You have to have both to do so. Some friends have the money but no time, and some have time but no money.
So I always end up flying alone. And it's fine by me ;-)
