What is the average hospital stay?

I am having an OPEN RNY on May 13 and my doctor told me the average stay is at least 4 - 5 days. I have been reading some of the questions and answers and saw that alot of people went home on the 2nd or 3rd day. Is it just because there is such a difference in the Open and the Lap?
