ok well i did it - one day at WDW and two at the rival park with the name that rhymes with toon-iniversal.
Day at WDW went like this:
Free shuttle from Hotel to Epcot
Didnt make Soarin, (big queue for this) Spaceship Earth
Mission: SPACE x 2 (no queues)
Test Track was closed
Boat to Hollywood Studios
Tower of Terror
Aerosmith Rollercoaster (EuroD one is better IMO)
Star Tours (this one is much better than at EuroD)
Bus to AK
Expedition Everest (this was probably the best ride of the day)
Kali River rapids (this was quite tame)
Bus to monorial - to MK
SPace Mountain (one at EuroD is better IMO)
Shuttle to Epcot
the world showcase
Very good - no issues/ worries as a single traveller at all. Disney staff are courteous and helpful and there are many other solos there (met with one on site).
