There isn't any other medication that has a high enough success rating that Cipro has. The time at the LFS to the time you're able to treat it could be the difference between life and death since the onset of the infection is hard to diagnose. If it's already sick, and it spends a week at the LFS without treatment, it may be too late by the time you start.
Ideally, you'll want to have your QT tank ready to go prior to receiving your anemone -- not a 60 gallon one, but a 10 gallon or so, or one that holds 10 gallons and the water level is high enough to more than cover the anemone. Your dosage of Cipro is typically based on the volume of water you're treating so you'll be using 6x as much Cipro as you would with a 10 gallon tank. If you have a large supply of Cipro then I guess it doesn't matter, though Minh's protocol requires a 50% water change every day so that's something else to consider.
I would take a look at it once you get back. If it looks okay, you can roll the dice and see how it goes. It may not even need treatment at all, though watch out for the warning signs -- deflation, expelling zoax, limp posture, etc.
