Wow. I thought the whole point of FT was to stretch the limits, and here everybody is coming down on the OP for thinking that he might be able to redistribute the 4 breakfasts he was entitled to

Rather than taking shots at the OP why not try to help him out ? This is a community, not a blog with a hoard of trolls in the comments.
The idea to give the kids the plat vouchers is a good one.
Otherwise chalk it down to experience, but my 2c is that the OPs expectation is reasonable, and such strict interpretation of the fine print is simply bad CS.

FWIW, I often forget to change number of guests from 1 when I make a rez when traveling with family, and have never, ever had an issue. I do check max occupancy for the room type, and never hide the size of the party when checking in.
