Thank you! We had seen before that our 30' motorhome was excluded. We called today and person answering phone said it was ok. We will call again next week to get a second person to confirm parking at the port is an option.
After I asked this question I found and called Gold Coast Car Rental and Parking. They said they can accommodate but we'd need to get our own transportation to port from their lot at 3000 se 6th Ave. Since we'll have 5 in the RV we're hoping to confirm parking at the port. Again, thanks so much.
