I agree, its not a real selling point for the BWPPI! But I think its more selection than the Desert's Inn (I may have read the same review you did on that one). One thing I don't like about BWPPI's breakfast is that you are not allowed to take items back to your room. My husband and son usually go over to eat while my dd and I get ready, then bring us back something to eat in the room. But they wouldn't let them do that. It was irritating, I always do that at the Tropicana and Camelot with no problem. You get vouchers, so as long as your vouchers match up with what you are taking off the buffet, what does it matter?
I do think you can upgrade your voucher for a more substantial breakfast at Captain Kidds but that place is so gross, I can't recommend that.
In essence, its enough to get your day going, but its pretty basic.
