Find five-and-a-half-story screens at the IMAX theater near the Audubon Aquarium (aquarium tickets include admission to the IMAX show of your choice). It can get pretty hot in New Orleans — especially during summer — and a few hours in an air-conditioned theater with some ice-cold soda is a great way to cool off from the heat and humidity. Films are shown almost every hour between 10 a.m. and 5 p.m.
