[Galadriel55]

That's an interesting view, Puddleglum. However, I'd say no to this because when Frodo departs from ME, it says that he could see light ahead, while Sam couldn't, and that happened withing a few hours of Frodo's departure at the most. It is most likely that the light comes from Valinor - where else from? especially since it is the light that only those on the ship can see (Frodo's ship went on the Straight Road and Sam didn't - obviously; so that is my explanation for the light).
Moreover, Ar Phazaron's juorney could have been longer than, for example, a Teleri's one (when they came to visit during the good times). He went to war against the Valar, and he was not counting on a strong breeze that would carry his ships all the way to Valinor. Although the Valar didn't stop him, they didn't help him either, whereas they could've eased and speeded up the journey for those who found the Straight Road.
