Although the summer months are very hot and humid you can have a great time in Florida. Think about heading to Crystal River on the Gulf Coast, you can swim with the Manatee and take diving lessons if you want... lots of diving at Crystal River. St. Pete Beach is fantastic! as well as Anna Maria Island near Bradenton. Catch a Devil Rays game in St. Petersburg and visit the Florida Aquarium in Tampa. A fun place to hang out is along Chanelside Drive in Downtown Tampa, nice atmosphere and tons to do.
To find
flights and airlines just check all of the airline web sites and of course the other places like Expedia but they don't have all of the airlines listed. I have found great deals from US Air and Delta... We moved to Tampa last June and played tourist all summer. We had a great time and are still exploring. Not sure where your coming from but West Jet has good fares from Ottawa.
