We're planning on visiting Chankanaab National Park with a 4 year old and twin 17 month olds. Are there certain things we shouldn't miss? Is the park accessible to strollers? (We'll have 2 umbrella strollers.) We're traveling with my parents as well so I'm hoping that the ratio of 4 adults to 3 little ones will give us some sanity. Any advice would be great! Thanks!
