We went in 2017 for about £4.5K, 2 adults 2 kids, 14 nights 20th January.
I'm a super budget traveller. We actually got a Virgin package for £1900, staying at Clarion Inn, Lake Buena Vista, which had free shuttles to the parks. We only did Disney, as had done Universal some years before. Hotel had pool and splash park.
The room had a fridge, so took butter, cheese, tinned ham, tuna, nutella, jam, cereal over in suitcase, along with heaps of carton drinks. Took loads of cereal bars and brioche from Aldi. Bread in the shops near the hotel was over £3 a loaf of worst white bread. So made a picnic lunch every day. I think we had a breakfast provided by hotel (or we ate the cereal!)
Signed up to various restaurants for vouchers, so had dinner out every night.
Not everyone's idea of a holiday, but hardly in the room and used hotel pool once, as went to parks daily and were exhausted on return.
Went to Celebration on the bus - stopping off at Walmart. That's nice. One night I took an Uber to Michaels to browse craft supplies. The exchange rate was too poor for shopping ($1.08 to the £). We did go to an outlet village, but only good if you're really into labels, and the Wallmart clothes, you might as well go to Asda!
I wouldn't do Disney again. I thought it disappointing compared to Universal.
However, because we didn't spend much, it didn't have to be a once in a lifetime thing, and am planning a return to orlando in a few years.
