Disneyland you can do in 1 day if you go on weekdays.
But is the exactly the same a onther disneyparcs.
Studio's is nice to go but every day very bussy and not a lot attractions.
If you want to sleep by disney, take a partner hotel and not a disneyhotel. The partnerhotels are the same, only you take in the morning a (free) shuttel buss to the parc. Think about Dream castle or Explore hotel... Book this not on the website but on hotels combineted dot com. there you find the best price.
Also you can go to Astrixparc. Nearly by Disney
But if you are in London and you go drive to Disney, maby you can better drive to Europapark or Phantasialand in Germany.
