We did the trip in a motorcycle a few days ago and did not keep track of cost. I would say the time would be about 3 hours and with stop 4 hours. We took the old road there and the new road back. It was a fabulous trip. We stayed at the hotel Florida (500p per night) and it was not too bad, but I would suggest another hotel is anyone offers something better. No one had pets, but I suspect they would be allowed at this location. You do not indicate that your staying extra day to see the sights so I will not go into that. I know this does not answer your questions much, but have a great trip.
