Hi, I live in the north of England and have visited WDW 7 times (and going again in Sept); and DLP 7 times - usually for the Christmas decorations, as when DH and I come to WDW we like to come Sept/ Oct time, so I miss the Christmas stuff.
Yes, it's freezing and we've been on the rides in snowstorms at times, but soon warm up with lots of hot choc around the log fire at Sequioa Lodge -and we still love going. We go for 3 nights/ 4 days and it's enough.
We don't compare DLP to WDW as they are different completely, in style, ambience, experiences, staff and our expectations.
Some rides are definitely better at DLP - Pirates and Space Mountain spring to mind. The Castle is a castle on 3 storeys, and not just a walk through parking area for strollers! The new Toy Story area and Crushes Coaster are excellent. The Studios park is becoming unrecognisable to when it first opened.
However if I had to choose one of them to visit , it would be WDW for the full vacation package - which for most of us from UK includes the rest of the Orlando attractions.
Interestingly - DH visited DLP once and won't go back; when I go it's a girls only trip.
DLP is still Disney - just not as you may know it
and if you get the chance, you should give it a try.
