2. Taking stupid pictures. Many times these pictures are of poor composition and quality. (Note the background is not level)
3. An aloha shirt is the sign of a tourist on holiday. Matching his and hers aloha shirts are an even surer sign.
4. Often tourists have information brochures, maps and other similar information in their hands.
5. Tourists wear clothing while on holiday that they would never be caught in dead where they really live! (this includes footwear)
6. Most tourists sport a silly don't have a care in the world smile on their faces. (And a big stack of credit card receipts in their pockets)
7. Pasty white legs! This is the surest way to spot a tourist in paradise.
