Decisions, Decisions

I am trying to decide which mobile broadband service to go with. My problem is knowing which one is going to work well in places like Mexico Beach. We go frequently and I would like to be able to do a little work when I am there. My other decision is whether to go with a usb device or give Verizon's new mobile wifi hotspot card a try. It acts like a wireless router and you can run up to 5 devices at once. I only wish I could find someone who has used it, guess I'll spend some more time visiting forums.
