Looking for something relaxing but still super-cool? Book a cruise with St. Pete Coastal Cruises to watch a gorgeous sunset near Fort De Soto Park, then see the Sunshine Skyway Bridge light up in brightly colored lights.
Dolphin-watching and nature cruises are also a lot of fun for people of all ages. Island Boat Adventures offers dolphin watching and snorkeling trips to beautiful Egmont Key.
If mom is the adventurous type, let her take the wheel and become the captain of her very own speed boat during a guided 1.5-hour tour.
Just want to relax with some great scenery and a cool drink? Several local companies offer floating tiki tours, including Florida Tiki Tours in Madeira Beach.
