Iam Landing on the 1st (to acclimatise) and flying back out on the 9th so that I have 3 solid days to explore and do a tour or two (guides welcome)

So 3 questions.
1 i presume its wise to bring some of your work with you. are cds and USB stick both acceptable? (figuring the usb would be easier for me & others to carry/ put in pockets)
2 File format and sample quality? eg AIFF 1579kbps 48Khz
3 Would you be better off picking a spread say of your 15-20 best pieces that show scope or have say 4 cds/ usb batchs with say 3-6 tracks on each. 1= drone music 2= cinematic/ theme 3= electronic 4= Guitar/ orchestral or something like that.
this might all be a Moo point, but need to know please
