When you are planning a trip, you are so excited about discovering new cities and finding out the best flight and accommodation deals that you might overlook some important details. When you're already there, how do friends' recommendations work for you? Was that expensive restaurant worth it? Was the museum what you expected? Was that sightseeing tour your best option? Did you get the best souvenirs for your friends without spending that much? Your limited time is as valuable as your money.
