Even if you don't bask on deck or on the beach, you still need to protect your skin from the sun. You should apply sunscreen to any exposed skin before you go sightseeing, and a hat offers extra protection to your face and neck. Aloe-based lotions can both soothe the pain and prevent some peeling. A burn severe enough to produce other symptoms, such as swelling or fever, should be treated by a doctor. You'll want to take home something besides a few matchbooks as mementos of your trip, and with a little effort, you can find fascinating souvenirs that will forever remind you of your vacation.
Stamps are another inexpensive and colorful keepsake.
And local clothing and accessories, often handmade with painstaking attention to detail, are wonderful wearable souvenirs. Bookstores are a good source for interesting, reasonably priced souvenirs. You'll probably find a variety of locally produced books, including novels, histories and handsome photographic volumes. Decorative maps and calendars are also lasting reminders of the ports you visit. Museum gift shops usually have an intriguing collection of souvenir items.
