Agreed. An 'almost 2yo' will want a playground, or perhaps the pool, or will want to sit and pick at a leaf all day.

That's why I asked if they are planning the holiday around a 2 year old, or if they actually want to see some sights. Bring the child, but still enjoy oneself is my suggestion, and don't plan a holiday for a toddler. They'll come along and find enjoyment in almost anything.
