If you're traveling alone in a double occupancy cabin, do you have to pay twice the required prepaid gratuities? The brochure says "prepaid gratuities per person based on double occupancy" and when I called them, they confirmed that I have to pay twice even if it's only 1 person traveling.

I'm a newbie when it comes to cruises but it doesn't seem fair I have to pay gratuities for 2 people if only 1 person is traveling. The cabin fare I understand but it's not like I'll be ordering for 2. The port fees, on the other hand, are indeed per person even if you're traveling solo.
