Considering the Rica Park Hotel Sandefjord in Sandefjord?
A VT member wrote the following comment about visiting Sandefjord:
travel to sweden by boat by Hildeal
The boat goes from Sandefjord to Stromstad, Sweeden. It takes around 3 hours. Enjoy the trip and all the food in the restaurant(knee supper), it's enough food for three hours
In Sweden you should take the advantage of all the cheap food there, before returning to Norway.
