Guam, a tropical paradise offers excellent historical landmarks and numerous sights of interest for everyone. Our Guam trip in last March was fabulous with my children and my parents. My children preferred more time to spend in water and they enjoyed the Gun Beach very much. We were staying in a hotel on Tumon Bay, which was very close to the attractions that include DFS Galleria, Underwater World, Game Works, The Sandcastle, The Globe, Tumon Sands Plaza, and Pleasure Island. My parents were happy to spend in historic monuments and museums and relaxed in the tropical beaches and explored the waterfalls. The best time of year to visit Guam is from January until May. During rainy season, there will be 80 inches of rain, so keep that in mind and plan your trip in dry season. Enjoy your time in Guam!
