Is there an instrument store in Tumon?
The two stores which I’ve personally visited are American Music in Tamuning which is temporarily closed due to smoke damage, the other one is Shimbros in Hagatna. I’m not sure if there’s an instrument store in Tumon but you can check out the Guam Phonebook for more info.
What should I wear when in Guam?
Light clothing, sturdy yet comfy shoes, sunglasses and sunblock. Don’t forget to bring your umbrella too.
How do I bring my family to Guam?
You didn’t mention for what purpose, is it for a vacation or to stay for a longer period of time? If you’re coming outside the United States and live in a country where you need a Visa to enter the US, by all means get the appropriate Visa. As you know there are various types of Visas – student, tourist, work visa, etc. If you’re traveling with your family on military assignment, please refer to this page.
