Travel Planning

My question to you today....is, do you spend much time on planning your vacations? I have heard that sites like kayaak and hipmunk offer the best airfares to give you a range of options? Are you someone that constantly checks airfares, to make sure you get the best price? Do you plan your wardrobe, coordinating it all, so that you can travel with less clothing? Do you research the area you are visiting, to see what are the attractions in the area? I love Virtual Tourist that offers reviews on the hotels, restaurants, sites to see... I would love to hear your stories and what do you obsess about.
