What you may also consider doing, is as following.

In BIDS, right click on your project name and select properties.

You will notice there is a Deployment utility section. On this section, select createDeploymentUtility = True.

Rebuild your package, and look at your \bin folder. In here you should now have a Deployment folder.

There should be a file created which is an integration services deployment manifesto.

If you open this file, this will open a package deployment wizard, which has a step in there which allows you to either select file system or SQL server deployment.

The nice thing about this utility is that it works with your variables, and that it deploys multiple packages within the same project together.
