Happy Friday! Needing some good Disneyland advice. (I haven't been in 15 years!)

We are thinking of taking our daughter for her 4th birthday (on a Tuesday in February) in lieu of a party. It will just be me, DH, birthday girl, and younger DD (18 months).

Give me the scoop.....this will be her first time! Any special birthday things they do for birthday kids? What about dining options? I know to have low expectations of what we will see and do haha. We are semi-local so we won't be spending the night. I do have a stroller question......should we bring the umbrella (Uppababy G-luxe) just for the 18 month old? Or should we bring our City Select with just one seat and the boogie board (bigger basket and 4 yr old can stand on bogie board if she gets tired? I don't anticipate the 4 year old wanting to/needing to nap).

Disney mamas....enlighten me! I'm seriously clueless....the last time I went I think they barely rolled out Fast Pass.......
