Any advice for traveling with a 2 year old in Honduras and Nicaragua?

Hey everyone... my friend and I will be traveling by rented car around Nicaragua and Honduras next month. This is our 2nd trip to the area but this time, we will be with a 2 year old. We'll mostly stay in Leon, San Juan del Sur and on Roatan island. Any recommendations on the best kids areas / safe, gentle tide, low slope beaches / parks / activities in those areas?

Also, any general advice?

Thanks so much!
