Great balance of planned activities, free time to explore, and other options if you wanted to participate in more opportunities. Our tour guide made the trip more enjoyable. He was so knowledgeable and organized. He paid attention to all the small details. The bus driver was great as well. We were glad that we went a day early to catch up on sleep and get acclimated to Reykjavík and the time difference. The bus transportation requires every person to have their own credit card account number. We tried to use our visa twice and the payment was declined.
