Has anyone brought your toddler,below 2 years old, for any group tours before? Are they able to sit through the coach ride? Will they make a lot of noise inside the coach and disturb the rest of the tour group?

I did!. I feel it if fine as i would keep talking to my baby to tell ans introduce the environmen to him. If he hungry, i would just breastfeed him or caddle him to sleep ... Should be fine and i think other would understand. Just ignore them if they complaint. After all, your intention is to bring your LO to explore and learn. So, dont worry...
