Using an higher ambiant value may help lightening the shadows.
Using radiosity may help but will take longer. Depending on your scene, 
you may need a recursion value of 2 to 6 (2 or 3 if you only have the 
ground and underside of the gazebo to considere)
If your gazebo is suposed to be canvas, try giving it a low filter or 
transmit value to simulate the light passing thrue the fabric.
Adding a faint light (Gray05 or Gray10) under the gazebo can sometimes help.
