My 9 month year old bella is going with us in 9 days.What should i bring with me? Sheets? Crate or Cage? The difference between cage and crate is it looks like this

I have both but i dont want to take both.

She sometimes wants to sit on my lap for car rides but this is a 2 or 3 hour trip should i let her?
