This is huge for us. Our suite already includes a microwave and fan. It is an option for other room types.
This is confusing for a guest when they are reserving the suite, as they think they must request a microwave in their room separately, even though there is one in the pictures and description of the room.

Super important. Currently we sell products online with a note that they only apply to certain room types, guests in the incorrect room types constantly add these. Particularly in properties who sell rooms and beds.

possibility to add a leadtime, for specific products hotel might need to order and prep in advance

Or specific rate of course... a breakfast included rate should not propose the product "breakfast".
