Hi, does the hotel rooms have attached / connected rooms with an internal door as would be booking for 2 adults and 3 kids and only see rooms that sleep 4
Sorry, not sure, but we booked a family room this year and it was very large (522). Would easily sleep 5 but might struggle for storage space.
No one mentioned adjoining rooms but there are family rooms with put you up beds cots etc available.
Probably worth emailing hotel direct as they are very helpful
