One of the suggestions from the people was going to Linnanmäki. We could do this Thursday 12.6. when there is free entry to the ferris wheel on the count of Helsinki day. Also there are couple of rides that are always free, but they will close already at 19.00. I suggest that we could go there two times that day. One group leaving 13.00 and one leaving 18.00. This way the kids have a change to enjoy the rides for more than an hour. More info about the park here
