I heard that rush hour is around 7:30-9:00 in the morning and 17:30-18:30 in the evening. Do we have to stand in line to get on the ferry. My daughter easily gets sea sick.. but I was advised it's a river ride so I shouldn't worry much. Has anyone gotten sea sick on the ferry? Thank you for your kind replies, in advance.

Next week will be my first visit to Europe from Japan. I will be staying at an Airbnb in Almada, could you share with me any ideas to show appreciation? (Examples, popular snacks in Japan, food, small items... also, if you could share with me what I should avoid would be helpful, too)
