Hey amigos
Don't forget to fill out your online FMM just incase they ask us for them at the border. If you fill it out and print now, it will save you the FMM fee which i think is around $25-$30 now and they will just stamp this printed out FMM and your good to go for 7 days.

For consistency, here is how I filled mine out. You guys will need to modify your depart dates.
