Moving long distance with fish

I have 3 tanks (20g and 55g freshwater, 20g saltwater) and I'm moving from FL to CO in a couple weeks. I'll probably have to get rid of the 20g tanks and fish, but I really want to keep the fish in the 55g. None of the LFS seem willing to board my fish and ship them when I get to CO. I've heard of plenty of people moving long distances with fish without problems, but here's the thing: I'm moving out of my house at the end of December, and won't be able to move into my new apartment until January 18. I'll be crashing at a relative's place for about a week, driving up, then living in a hotel for about a week. My new job starts on January 13th, so leaving to arrive on the 18th isn't an option.

Is there anything I can do? Maybe set up the tank at my relative's place, then set up the tank in the hotel room?

Failing that, does anyone in south FL want some nice semi-aggressive community fish?

Thanks for the replies. None of them are particularly rare (boesemani rainbowfish, irian red rainbowfish, yo-yo loaches, albino Buenos Aries tetras), but I've had some of them for around 3 years and would hate to see them go to someone who won't take care of them. I remembered that I have a friend who breeds cichlids in central FL... gonna see if he's willing to take care of the fish and ship them once I get all set up in CO. Failing that, I guess I will have to find a new home for them here.
