If any of you are planning a trip down to the Keys and (1) a lot of people are involved and (2) you're on a strict budget, I found the 'deal of the century' the other day while cruising by the motels dropping off brochures.
The name of the place is Conch On Inn, home site is www.conchoninn.com. It's about 8 miles south of Key Largo and 3 miles south of my dive boat biz.
It's a small place with 4 duplexes divided into 8 rooms. The deal is, rent all 8 rooms and together they're only $400/night. Given that the average room around here is probably $150/night, only having to cough up fifty bucks is outstanding. The place is no great shakes (it looks better on their web site than it really is), but for that kind of dough, who needs amenities?
