Disneyland Hotel is closed for refurbishment.
A note about pools and Disneyland Paris. It is not like Walt Disney World or Disneyland California where people take a pool break in the middle of the afternoon. The Disneyland Paris hotels are not resorts and people spend most of their time in the parks.
Disneyland Paris is built for European guests and what they expect and need. For Europeans the pools are just a nice bonus. Americans used to Walt Disney World will be disappointed with the hotels in Disneyland Paris.
