This tour is pricey, but we had an amazing time seeing inside the Palace. Pay attention to your ticket time (we stupidly confabulated it with something else and almost didn't get to go), show up fifteen minutes early like they ask you to, etc, and then just luxuriate and enjoy. When we were escorted out, we were taken across the front area, under the balcony where the royals often gather to wave at the crowds. The tour guides were knowledgeable, the rooms are breathtaking and fascinating and special, and the Champagne at the end was really pretty good, which is always a surprise at this stuff. DEFINITELY go, especially as right now, it is only open at very limited times. Book in advance. It's open in August and sometimes the end of July, and sometimes in winter, January/February.
