I've moved my reef twice ... from my experience, you should plan to dedicate an entire day to the tank, simply because it can take longer than you might expect and you shouldn't be burdened with other moving related issues.
You'll need buckets. Bags for corals, fish. Keep as much water as possible. You'll need to have some new saltwater ready to go at the new site because you will lose some water in the process.
Try to not disturb your substrate when moving. Leave it in the tank if possible. If you have to disturb it (DSB too heavy), you'll need to replace it because it will release a lot of crud into your system.
Watch the temperature in your livestock buckets... you may want to stick a small heater in there to maintain good temps for your critters while you're setting up the tank at the new location.
Fish are easier to catch if you drain the tank down to 3" or so ... remove all the rocks and corals first. Fish last. They're easier netted in shallow water.
Your reef will look great after you set it back up. After a week or so, you'll probably get an algae bloom ... just maintain regular water changes and the system should stabilize without much trouble.
This is also a good opportunity for any upgrades to plumbing, etc.
Good luck moving! 25 mins away isn't too bad ... it's going to be work, but if you have a helper and think out every step before executing, you'll definitely deserve a beer when finished
