Can't imagine what your problem couldl be. We are going from Flint to Grenada next month using points. Of course it is not direct and will take all day but no overnights. We have had to do overnights on occasion when we leave booking until the last minute but still using points. Once we opted to spend a couple of days in South Beach, so that just extended the vacation. If you went thru Flint tho. you'd still overnight here, since the flight to Chicago leaves @ 6:00 AM. We used to go to different islands flying from Detroit and then we would usually overnight @ a Park & Stay Hotel. But that overnight thing is added expense and a pain in the neck unless you are staying somewhere warm and fun!
