I have searched through the forum, but can't quite find what I'm looking for. We are staying 4 night/5 days next February half term in the Disneyland Hotel. This trip is for my 30th Birthday

and where we normally stay in Santa Fe or the Cheyenne, which we loved by the way, and stick to the budget restaurants or counter service options, we are considering paying for a half board option and trying out the higher end places.
We are torn between Half Board Plus and Half Board Premium. Can anyone give me any idea of the Pros and Cons of either one, or both if you are lucky enough to have tried both
Our kids are fussy ish eaters and although there are plenty of options for me and my husband in places like Auberge or the Blue Lagoon, I'm not sure we'd get our moneys worth with the kids in these places. But we 100% want to do Buffalo Bills again and Inventions, which are both included in the Premium option. We also want to go to Walts.
According to the Disneyland Paris website E-Brochure, the Premium option would allow us to go A La Carte. Does this mean we could literally choose anything on the menu? Or is there some small print somewhere?
Thank you in advance for any advice you could offer me.
