I'm looking for suggestions on ferries out of Stockholm. I'd like to pass through the archipelago during daylight (early morning or evening is fine) at least once.
Is it best to book a room on the ferry and travel overnight? Are fast ferries better options for some legs (e.g. Helsinki to Tallinn)? I've been to both Helsinki and Tallinn, but my wife hasn't visited either. This would be a stop for a day of walking around the center. Not planning to overnight unless it makes sense to add.
Can it be turned from a triangle route to a square and end in Visby? I'd then need advice on Visby to mainland with an idea of them renting a car to see some smaller towns enroute to Gothenburg.
Finally, recommended website for schedule and to book passage?
Thanks for your help.
