I've done it for the last 3 times I've gone solo, and I've been glad I did. Just the fact that I'd prepaid a set amount for food made me feel a lot better-otherwise I tend to fear (and it turns out true) shock when I see how much I've charged! However, as has already been mentioned in 2008, I really don't think it's worth it. I've got one more solo DDP trip coming up in November/December. Planning on going out "with a bang", that is, a lobster at Narcoose's. I don't think I'll be having that much after this year.
