I went there several years ago. Can't remember what the name of the motel complex we stayed at but it had a pool and such and was pretty reasonable.
Quite a few of them around Islamorada. They also had a big walkway that went right out in the Atlantic that was cool.

We fished 5 days for Tarpon out of Bud and Marys Marina. They are the bigtime guiding outfit there and are on the left side of the highway as you a driving towards Key West.

They have the flats type boats and the offshore boats there.

We fished with a guide by the name of Richie Amoratti and was a pretty good guide but not to talkative. We fished for Tarpon with floats and live Mullet and was not to exciting until you "jumped" one then all heck broke loose. Caught some Tarpon and Barracuda.
I got one at 150 pounds and took 65 minutes to land. Man, they can jump 15 feet straight up and you can hear their gills rattlin'.

Way to much heat for me wearing levi's, flannel shirt and a coyboy hat. If I went back I would get some cooler clothing.

Have a good time and take lotsa pictures. I took a bunch and enjoy looking at them from time to time.
