Nynashamn to Stockholm

I'll be on the Regal Princess when she goes to Stockholm on August 16th. My paperwork says we tender at Nynashamn.

Somewhere I read there's a floating dock there and it's not a tender. Someone else on these boards said they went through the archipelago on the Regal. Perhaps it varies?

If we do tender at Nynashamn is there a train or bus that would take us easily into Stockholm?

Sometimes Regal P berths at Nynäshamn where you will use a retractable pier to disembark. Sometimes RP berths in central Stockholm.

From Nynäshamn you have a few different options.

Walk or shuttle bus from pier to railway station and commuter train from there.

Use the ship's shuttle bus if there is any.

Go on an organized tour.
