I really enjoyed this tour. The scenery on the way to Pena Palace was beautiful. The tour guide did a good job informing everyone of its history, inside and out. My only criticism is she was talking to the us in three different languages, which had to be difficult. So she had to cram in a lot of information each time. I realize that Viator does this in order to fill the bus, so to speak, and make more profit. However, at times the different languages running one after the other, was confusing and left little time for visitors to ask questions because the guide was rattling off so much information in a short amount of time. You had to pay very close attention or you would miss her comments.
