I have been planning this trip for a while now.  I have been to Stockholm twice before, once in the early 2000s and more recently a few years ago.  Escape rooms were certainly not a thing on either trip.  I am looking forward to going back to such a beautiful city.  I have a couple of days in Stockholm then fly to Helsinki.  I had hoped to get the ferry but it will shave to much time off the trip.  I then have a few days in Helsinki, a place I have always wanted to visit.  The ferry to Tallin shouldn’t take more than two hours.  Staying in the old town means I shall be well placed to access the growing number of escape rooms.  

I would have liked to have tagged St Peterberg on the end but to do that trip properly I think you would need at least 10 days.  I will share my itinerary when things are more firmed up.  I want to strike the right balance between enjoying the city and enjoying the escape rooms they have to offer.
