The Moorings/Sunsail mifi rental is highway robbery. If you have a spare smartphone, a digicell sim and 3gigs data would be about 1/3 the cost.

If you don't have a hotspot capable smartphone handy, you can walk onto the digicell store, purchase a mifi router and all the data you need for less than the Sunsail weekly rental. And then you would have a router ready to go next time.
