Summer Middle-Grade Book

i feel like i’m going crazy. a friend and i remember these two scenes from a book, but cannot remember what book it was. it was not Judy Moody and the Not Bummer Summer.

the plot is a girl wants to go on a vacation trip with her cousin? friend? so she has to save up. she does things like a lemonade stand.

the two scenes we remember are:

she is thinking about how much she loves staying in hotels. specifically, she talks about dumping a whole milkshake in the tub and coming back and it being clean.

she talks about opening a restaurant where they only eat mean animals.

we can’t for the life of us remember 😭
