If you have plan coming back to
Disneyland Paris again in the next 12 months, its cheaper buying Annual Passes and staying off-site.
Ive been at Kyriad once (quite good hotel) and Holiday Inn three times (much better, but also more expensive), and its very easy getting to/from the park (free shuttle).
But if this will be the only trip for one year, I suggest to stay on-site.
You will never forget your first holiday in the Paris Magic Kingdom, and staying in one of the Disney hotel you will be able to breathe the Disney Magic every single second of your trip!
PS
No, I dont sell Disney packages, I swear!
Jocking apart, I dont think packages are so expensive, because you get:
- Hotel
- Breakfast
- Tickets valid from the morning of check-in day until the evening of check-out day
So, the first day you can also arrive early at the hotel, check-in and, if the room isnt ready, leave your luggage (for free), take tickets (they give them immediately), enjoy the day at the parks, then go back to the hotel (after early afternoon, but whenever you want, also late evening) and take key for the room. Or, the last day, if you leave late, you can check-out in the morning, leave luggage, visit parks, go back to the hotel to get your luggage and leave.
Oh, and being a guest of a Disney hotel you can use Extra Magic Hours!
I hope this can help you (for me it was a good way to practice my poor english writing!)
