As I mentioned before I would like to share my family trip itinerary. My family members are 11 from the age 6 to 70. For everyone’s benefit, I tried to adapt the various interests of most family members. We didn’t always stick to our plan due to weather and the time limit.
Anyone who doesn’t know where to begin, hope this can be helpful.
