Bonjour David and welcome to planDisney!
How exciting that you're planning a trip to
Disneyland Paris! As I am based in the UK, my family are frequent visitors and I have to say that, in my opinion,
Sleeping Beauty Castle is definitely the fairest of them all! Be sure to also check out
La Tanière du Dragon when you visit.
When booking a
Hotel + Ticket package, directly with Disneyland Paris, park tickets are included for every day of your stay, including both arrival and departure days. So, if you were to book a 2-night Hotel + Ticket package, this would include a 3-day park ticket.
Unfortunately, the only way to make room only reservations, is by
calling the Client Relation Center. I appreciate that this isn't ideal as it involves making a long-distance telephone call. My only other suggestion would be to price up a room only reservation via a third party travel agent such as Expedia or Booking.com etc and then add on the cost of 1-day park tickets which you will be able to find on the Disneyland Paris website.
Just so that you know, David, as park tickets are highly discounted when included as part of a Hotel + Ticket package, you may find that there isn't much difference in cost between a 2-night room only reservation plus 1-day park tickets and a 2-night Hotel + Ticket package.
I'm sorry that this likely isn't the answer that you were hoping for. If, however, we can be of any further assistance with the planning of your summer trip to Disneyland Paris, you know where to find us.
Wishing you a magical trip filled with memories which will last a lifetime!
