My pleasure!!!
These are the prices I got:
Disneyland Hotel (deluxe) £1816
Hotel New York (deluxe) £1242
Newport Bay Club (moderate) £1102
Sequoia Lodge (moderate) £ 1030
Cheyenne (value) £946
If you don't mind my asking, if the 5th member of your group is a baby you could have a crib in your room as well as 2 double beds.
I wouldn't say I was an expert but it sounds like the Disneyland Hotel would suit you - but the Hotel New York and Newport Bay Club are pretty upmarket and near to the parks. We like the Sequoia Lodge too.
Ask any more questions - glad to help!!
