When you're on your own, you're independent and in control. You can travel at your own pace, do the things that interest you, eat where and when you like, and splurge where you want to splurge. You don't have to wait for your partner to pack up, and you never need to negotiate where to eat or when to call it a day. You go where you want, when you want, and you can get the heck out of that stuffy museum when all the Monets start to blur together.
