I don't think they stayed on Thriller Bark for one day.

Also the manga doesn't cover everything that the Strawhats do. There would be some time between one arc and the next but readers don't want to read that because those scenes would be a waste of the time for them.

Also, they fought for each others lives. Can hardly call that a weak bond if they went through hell together.
