Civil ceremony requires blood work (totally safe and they come right to the hotel $150'ish), the symbolic does not require blood work.
I have read the bus ride is close to 2 hours due to all the stops at other hotels - been told its worth paying for a bus.
There are a million photos of the whole resort at tripadvisor.com.
Again, this is all info I've read, not my own experience. Loads of info on tripadvisor.
