We went begining of July.
Direct flights for 3 cost under £2k (eldest is classed as an adult and I paid extra to sit together as they were messing about with seating so you could do it cheaper if you wanted to)
Hotel s/c appartment with breakfast, coffee/tea on tap all day, pool, gym, bbq area, free buses to Disney and token cost to Universal, and other amenities £1200 for 2 weeks (no more than some of the euro' holiday places I looked at)
Unlimited 14 day passes to all Disney and Universal parks £1300 (both kids classed as adults) (not seaworld)
We took £4k spending money as not driving and didnt want to run short of money for transport, tips, shopping etc. Brought over £1k back.
It was a great holiday, so many memories, kids first time abroad so made it memorable
Its not just the rides it the whole place, there is so much detail, so much to see and do, Disney was great too, Epcot fireworks/lazer display was stunning And the thunder and lightning storms at night were a free show 
I am so glad we were able to do it, hell never mind the kids I have always wanted to go to Universal
and due to circumstances I could afford it and thought it was now or never!
If its something you want to do, if you can afford it then it isnt an expensive waste of money, its your holiday, your choice.
