What makes Orlando pricing move
Orlando is dominated by Walt Disney World, Universal Orlando, SeaWorld, and a dense ring of resort areas — Disney property, Lake Buena Vista, International Drive (I-Drive), the Universal area and Kissimmee. Hotel rates in every one of those areas move with the park calendars: Disney's seasonal pricing tiers, Universal's Halloween Horror Nights, EPCOT festivals, marathon weekends and US school breaks all create predictable spikes.
Add UK school holidays and the BA / Virgin / TUI capacity from Gatwick, Heathrow and Manchester, and you get a pricing graph with very obvious cheap and expensive weeks. The cheap weeks aren't secrets — they're just hard to find when every site is shouting 'from £XYZ' at you.
