SQL server data transfer scenario

Hi All,

Here is the scenario.

Site 1 - Primary DB - A -- this is a transactional OLTP Db

Site 2 - Staging  

Site 3 - Destination 

requirement is to replicate(I mean, copy all transactional data) from Site 1 to Site 2 first and then to Site 3. We cannot go directly from Site 1 to Site 3 as Site 2 will be used by more than 1 team..

Option 1 
Setup replication from Site 1 to Site 2 and then from Site 2 to Site 3 (This is NOT recommended, its called DAISY CHAINING, am I correct?)

Option 2
Setup replication from Site 1 to Site 2
Then write scripts to INSERT INTO SELECT (basically INSERT INTO Site 3 DB in an incremental manner)

Are these the only options or is there any other? What are pros and cons that you guys think??
