When I go on vacation for more than 3 days then I usually employ my brother-in-law to come by and take care of it. He has a 75 gallon FOWLR so he is familiar with what to do most of the time.
If it is 3 days or less I don't have him come over, the fish can go that long by scavenging around the tank and the corals, IME, will be fine for a weekend.
