At this time of the year it's a nice time to visit a botanical garden.
Close to Downtown Orlando is Harry P Leu Gardens at 1920 N Forest Ave, Orlando, FL 32803.
These beautiful historic gardens not only offer the visitor a relaxing few hours of tranquility but have scheduled events, such as the 'Dinosaur Invasion' which has been running since January and ends on April 30th 2017. There is a movie night on selected evenings, and 'Story Time' for the little ones. Also Leu Gardens is a wonderful wedding venue.
