We've booked a two bedroomed 'cabin' at Davy Crocketts it seemed the only way we could have a seperate bedroom to the kids. But am now wondering how / where they will sleep. I think the second bedroom has bunk beds - will the top bunk be ok for a 5 year old? Does the bottom bunk have a rail to contain our dd2 which will be 2 years and 1 month! Any experience anyone??
