If you've bought a Stockholm Pass, this visit will get you your money's worth for the day, as the cost of the roundtrip ferry plus admission is probably the most costly item covered by the pass.
Stockholm, aka Venice of the North, is a city of waters and ferries. So sometimes the catch is going to the right pier and catching the right ferry. If you have the Stockholm Pass, you'll catch the ferry at the pier outside City Hall.
TIP: If you have time, arrive early and allow two hours to visit the World famous Stockholm City Hall where the annual Nobel Prize banquet is held.
The ferry ride was very crowded so if you want good seats, get in line early to grab them. Nevertheless, the ride was very scenic and relaxing.
It was a short and beautiful walk from the pier at Drottningholm island to the palace which was punctuated with many photo ops.
Like several Yelpers have said, the palace is not Versailles, so you need to keep your expectations reasonable. On the other hand, you don't get the crazy crowds and impossible lines at Versailles either.
This is still a very nice palace, and it does give you an opportunity to experience Swedish royalty. There's a guided tour which gives you a lot of insight, such as who lived where and why. It was also interesting to know that numerous guards lived inside the palace and were positioned in strategic places.
If you need food, the only café is outside the palace. I would recommend visiting the palace first, go grab food outside afterwards, and then tour the HUGE outside gardens and the Chinese Pavilion, among other places.
On a side note, the food at the café was great. The open face shrimp sandwich (which is a staple in Sweden) was amazing. If you ever find yourself in the street of Stockholm, this is a must try.
