There are 6 onsite hotels at
Disneyland Paris, Santa Fe and Cheyenne are family friendly budget, Newport Bay, Sequoia and New York are mid price and Disneyland Hotel is top price.
All 6 hotels give guests access to the morning EMH.
The hotels are priced according to distance from the park entrance, facilities / services and room /hotel layout and decor.
Disneyland Hotel is the closest to the park, its actually located above the park entrance turn-styles. The decor / layout, services, restaurants etc all reflect the higher room price. It is the only hotel which has views into the park.
Also bare in mind that the prices listed on Disneyland Paris are package prices. Unlike the USA parks, Disneyland Paris prices include park hopper tickets for both arrival day and departure day.
Take a look at the different country websites. You dont have to book using the website for you home county. I am from Ireland and for my last trip in February 2016, I booked using the French website. Different countries have different deals and offers and prices as each country has a different touring style.
