Disneyland for a 20 month old toddler is just not worth it, really.
For Hôtels, we use the Citadines that have a fridge and very small cooking area- not proper kitchen. There are several in Paris- we like the one in Le Marais- as we like the area and it is close to Gare de Lyon as we always go by TGV train (much better than flight as it takes you straight into town). www.citadines.com/fr/index.html
The 1 bedroom apartments have full kitchen.
