Pena Palace, Sintra, Portugal should I go there?

If you thinking whether you should go to Pena Palace in Sintra, Portugal (just outside of Lisbon) then you should watch this video to know what to expect. It is busy and I believe, overall, it is worth it but you may not. Watch the beginning and, if you just want to decide quickly, skip to the middle of the video and then skip toward the end when I give a summary of thoughts.
