We are are going to Cozumel with another couple whom we really like. They have kids our age and we all get along. Out of the blue, both my husband and her husband invited another couple and I do not like the woman, she flirts with my husband and the other husband and texts them, etc. Also she has an out of control 16 year old daughter who I don't want around my family. We are supposed to share a house and it has been picked out and held by her already, what do I do???!!!
