Explorer - decks 4 & 5 outside cabins - portholes

[hlperez]

Does anyone know which outside cabins on decks 4 and 5 have portholes instead of picture windows?  I am wondering whether it's worth paying the extra to choose the room, as I don't particularly want a porthole?

Thanks

If you look on the deck plans on the marella web site it marks the cabins with portholes.
It's only a few right at the front of the ship, 7 on each side on deck 5 and 1 each side on deck 4.

For the £50 charge I find it worth selecting a cabin for location anyway.
