Florida vacation - find good deals

I have booked for a Florida (Miami, Ft. Lauderdale and Florida Keys) during last week of August.
Been trying to search for a deal/discount in AIR TOURS : helicopter, hot air balloon- Can anybody help me in choosing one with a slick deal? Or plz share your experience if you have taken any air tours.

We are a couple and want to know if shelling out a decent price on a Miami coast line helicopter tour is worth or a hot air balloon ride is better over the same place. Is there an air tour from Miami to Florida keys (Key West) worth trying?

P.S: Price and the excitement/thrill/sight matter. We have never taken a helicopter tour.

Tip from me to others who are travelling: Fort Lauder dale can be seen with deep discounts using the coupons found in http://www.sunny.org/includes/med...oupon4.pdf

BOGO free deals on every tour and entry tickets.

- your time appreciated!
