Need help picking Carnival Valor rooms

[ahamlet]

I booked a Jan 2017 interior room for myself and what will be a 16 yr old DD, 15 yr old DA and 11 yr old DA at the time of the cruise. After looking at youtube videos and pics online I fell in love with a grand scenic view room on the lido deck. It's appx. 320 sq feet. For $90 more I could book to scenic view rooms. Which would give us 2 bathrooms. Which is the better option? All advice will be greatly appreciated.
