I think there is so much to see in Edinburgh that the accomodation should be there not Glasgow, spend a half day in Glasgow and two in Edinburgh, 4 hrs is not enough time to see anything. A night in Belfast would be good, not just a drive thru the City. Dublin to see a lot you need at a full day, there should be enough time in Windsor to some exploring.
