Can anyone recommend a carry-on suitcase? I am going to Vegas for 4 days and I don't want to check my bag. I think I have the clothes picked out to mix and match, and am taking just enough. If I buy anything, I will have to ship home. The last time I flew, the airline lost my suitcase. Oh- the more obnoxious the color the better. I have a LV 45 keepall, but I want wheels I think. Thanks.
