I might be wrong, but I think you can. They were working on a walkway around the 7 seas lagoon and from the monorail it looks like that section is complete. I thought I saw a sign b/w the resort monorail and the boat launch to the GF that directs you to the walkway. If it is complete, that is the way you would go and it would not be too bad of a walk, longer than walking to the CR though.
