I suspect they call for 3" thick because that's 2 layers of 2"x ??
dimensional lumber laid at right angles and nailed together. I'd use
pressure treated 2x8's without any glue just enough nails to keep it
from moving. The weight of the gazebo is straight downwithout any
movement. I think that's the cheapest and quickest solution although
you've had lots of suggestions that will all work well. Whatever you
decide to do you need to put a moisture barier between the wood and
the concrete a piece of tar paper would work best.
