Hrh questions - club level

Hi All , Happy New Year!

Few questions regarding HRH. We are a family of 5 planning to stay in Deluxe Queen room with sofa bed. My questions are

-Do I have to pay extra for a fifth person even if I don’t need a rollaway ( my kids will be 8,11 & 16)?
-Are microwaves available in the rooms?
-Does anyone have any reviews of the club level lounge in terms of the type of food offered and is it worth the money?
