here is what I suggest:

if you are a US citizen, go thru immigration (approx 10min wasted) and check into a hotel nearby. Get your bags and give them to the bagage hold service (pick them up when you come back.)

check into a day hotel, get a hot shower, breakfast and sleep all day. this way you will be rested and will nto be bothered by anyone walking/talking around you.

this is what I would do since I like to be rest without any disturbance !!!
