Port Orleans Riverside - Requesting Specific Rooms?

Hi, can anyone advise what building or even rooms would be good to request? I have 3 kids 4 and under, so we want to be close to transportation. We booked a Preferred Room. Ours will have the Pull out bed option, but I don’t think my in-laws booked that option though they’re Preferred. Can anyone recommend rooms to request? Is upper or lower better? Thanks!

I’d request building 14, (closer to amenities, lower floor, because of stroller/s.)
