How do you take more than one pokemon at a time from the DW to the Entralink?

DW = Dream World. So, how do you take more than one pokemon from the dream world at a time.I made my wish then went back home right. I tried to go back to the island of dreams but it said i had to take thenpokemon to the entralink. I wanted to like go back to the island of dreams to make another wish ok. But what is the most important part is that how do i take more than 1 pokemon from the Dream World to the Entralink. Do i have to wait day for day for the rainbow bridge to come back to make another wish? Or do i have to take the pokemon 1 by 1?
