One further note:
If you take the tram from the parking lot at the TTC, it will discharge you on the sidewalk in front of the booths that sell tickets. When you get off the tram, don't follow the crowd. Instead, turn to your left and start walking down the sidewalk. You will see the Poly in the distance over the trees. Right before you reach the end of the sidewalk (likely about a 100 yard walk), there is a sign that says "Polynesian Village Resort". Walk across the one or two car access road to the next sidewalk. Follow that sidewalk. It will take you right to the Grand Ceremonial House.
If you get confused, there are always CM's nearby.
