This is our first cruise. We're considering engaging a car and driver from the pier at Nynhamn to take us into Stockholm and sight-see for a few hours. However, we don't know what time we will get off the ship. Assuming we were ready to board the tender at 0830, how long would it take to get to the pier, and how does one get tickets--assuming they are required--for the tenders? Do they run all day? Advice, please!
