Corals before fish?

[Easto]

I have most of my equipment and supplies to get my tank running in the new year to cycle my dry rock.

I am going on vacation in March for 2 weeks so I would rather add fish after I get back so I don't have to deal with an automatic feeder, etc.

I was thinking (and I think it's a little ass backwards from the norm) would there be any problem adding some beginner easy to keep corals in the tank when it's done cycling before the fish go in?
