I went on this tour with my husband and 19mos old. Definitely doable with a toddler, plenty of space for them to stretch their legs and run around safely. Wear good shoes! Lots of photo opportunities. Sonny Chuong was our tour guide and he and the other staff were excellent! Chuong was very enthusiastic from start to finish, friendly, knowledgeable, and very accommodating with our baby. The lunch on the cruise was delicious Vietnamese fare, tropical fruits, and evening fruit with crackers, wine, or tea. I would recommend this trip to anyone, including families. Don’t be scared!
