What sort of filter do you have disneyworld? If you still have just the smaller fish like guppies, I would keep them in a spare plastic container (a bucket or barrel perhaps) with the heater and filter running in it. They will survive a week. That way when you set the tank up again you won't have to cycle it, if the tank isn't overstocked. You will get a mini cycle, depending on how much water you can save but if you can keep the filter running it will be easy.
Good luck with the shift.
