The tour of the Imperial Museum was done much too fast. The company's guide gave no time to look at things or to ask questions. In addition, he did not leave any time to see the gardens. Considering that it is about a three hour round trip to get there, the half-hour tour of the museum was wholly inadequate.. Stop at the Chocolate Factory on the way up was a waste of time and could have been skipped to leave more time for the museum. I would avoid the company if I ever get to go to Brazil again. Don't pay extra for the Crystal Palace! We didn't and we saw everything there was to see!
