if you really want to go back to Florida I would cut the holiday to 12 nights , spend 5 nights or less at universal and then go to the coast for the remainder, which would make it cheaper. . We did that on our last trip(Anna Maria) and was our best Florida holiday.
Equally we have done Europe for cheaper than £6000 and had just a good as time. Despite it being a so called "beach holiday" we have just as many trips out and are kept equally as busy and have never spent all day on the beach, my children preferred Europe to Orlando.
I would have a family discussion as to where everyone would prefer to go though as I think that's fair . Sometimes a change is good!
