The packages are different for Wishes and Escape.
For Wishes, they seem to usually send out two photographers.
What you have to do to get the high-res disc of images in a swap varies depending on which of their packages you select. If you pick the $5,225 one, you can get it free by giving up all the prints and all the albums. For the $3,650 package, you have to give all that up and pay an extra $200. For the $2,800 package, you give up the printed products and pay $400.
For Escape, it's a whole 'nother ball of wax...
