I am but we will be on a cruise that stops at several greek islands. When is your wedding? I am going in September so I can fill you in when I'm back but that might be too late for you.
I stayed at Atlantis Villas on Santorini. It was in the quiter part of town which I suggest you stay in.
It was definitely one of the nicer ones on the Island. There seemed to be another one just above Atlantis Villas that was just as nice if not better. A travel agent should be able to help you.
I booked everything myself directly.
We enjoyed Santorini. We stayed there for 8 nights which I think was a bit much. We did a day trip to Ios by boat. Once on Ios we rented a car and went on some crazy, scary road to the other side of the island. Once there we found the greatest beach. At first we were the only ones but then a few other couples showed up but not many. The beach is so hard to get to that it is pretty secluded.
On Santorini you should definitely go to a restaurant named 'Old Mines'. They have great food and the best sunsets.
I think you should try to go to at least one more island if not two.
Here are some of the sites I used:

fodors.com
concierge.com
I used the discussion sections of fodor's and concierge. I also looked at the hotels they recommended.
I went to Santorini the last two weeks in August. The weather was great. It was definitely hot but not unbearable. If you have any other questions let me know. Also we stayed one night in Athens. For us that was more than enough.
Athens wasn't that bad. It was just a little crowded and noisy. I was flying to Santorini from England and there were no direct flights. It worked out best for us to fly to Athens, stay overnight and then fly to Santorini.
Enjoy yourself.
