Thank you! We're staying at POR. We tried to book at the Dolphin, but found it to be more expensive. Do you know approx. how much a cab would cost from the CCC to POR? It just seems so silly to return a rental car, only to have to catch a cab! Do you think the walk to the TTC or Poly is safe late at night with no sidewalk?
I think it's reasonably well lit, but I'd feel a little weird about the first half when you're walking next to the road with cars going by. Once you're in the parking lot, you're as safe as, well, walking in the WDW parking lot. You might even be able to catch a parking tram.
You could certainly go, scope it out, and if it looks sketchy call a cab. There will be several right around the corner at the Poly and GF, so you shouldn't have to wait more than a few minutes. And if you take the cab back to the TTC and pick up a bus from there, the cab ride will cost you less than $5. All the way back to POR will be $20 or so.
But one strategy is to go ahead and book at the CCC, then once it's booked call up customer service and ask them if you can return it at the Dolphin. They might - emphasis
might - just tell you to go ahead. The price might be set based on where you pick up, and they don't care where you return it as long as it's at WDW. That might not work, but it's certainly worth a few minutes to try.
Also, did you check Shades of Green? That's another place that's easy to get a cab from. It might even be possible to hop a shuttle to the TTC from there. You're allowed to go in to rent a car even if you're not military or ex-military.
