What should I do?????????

My husband and I are on vacation in Mexico. We been hear six days and are planning to leave in two days. Last night, my husband started to get sick and this morning he woke up all achy and feverish. My friend and her husband are also here and I was talking to them, and she said if he wasnt better when it was time to leave, that maybe we should just stay here till he is. I can kind of see her point, i wouldn't want to be uncomfortable on the plane and travelling probably wouldn't be good for him while he is sick. At first I thought I should just find an earlier flight before he got any worse, so he could at least be home in his own bed. I'm really not sure what to do.
