I have been over twice..both times with the dog. Lots...most..people have dogs on-board. You cannot take your dogs up on the decks, no. You leave you pet in the RV. You are allowed down once to ensure all is well...they announce that. Yes, the crossing can be rough..it is the Hecate Straight..one of the most cantankerous sections of water on the west coast.
If you do go...the ferry departs at night from Pr Rupert. A suggestion is to pay the extra and get a stateroom (Reserve same time as booking ride). We did this both times...the folks up on the decks can be..uhmmm...boisterous and at 2 or 3 am, when you wanna be napping? maybe not going to happen. Coming back to the mainland is a day run, so you are up on deck watching. And really? there isn't that much to ohh and awe over.
As for what to do and see. First off..it is pretty expensive so plan to stay at least a week. If you do? and stay in your RV and boondock? you are in the black. There are lots of hotel/motel/cabins/B&Bs too..but if you are in the RV, use it. You have to be skilled at boondocking over there, if that is your plan. It is not a heavily populated area and in fact, some folks find it boring. If you love to walk beaches and collect agates? shells? sit and watch eagles and just hang-out? you'll love it. There is an hour and a half drive from Queen Charlotte City to Massett. That is strong Haida country and it's kind of..different. If you do go to Massett? and have need of anything..let me know and I can put you in touch with folks that will assist.
Also..again, if you go? take the ferry over to Sandspit..there is a fabulous Provincial Park and again...you just hang-out. But plan on going for a couple 4 days. The cost of going over to Sandspit kind of irks..so, make the best of it.
Haida Gwaii travel is best suited to a truck-camper or a shorter C. I am thinking of boondocking, when I say this. If you are running a large set-up? the paved roads and so on, are fine..but to get off the beaten path? you need versatility.
Here is the beginning of our 3 week trip last year. It has eight Blog posts...you'll need to scroll down to the end of each page and poke the 'Newer Post' button.

http://mrgwh.blogspot.ca/2013/09/boarding-ferry-to-or-from-haida-gwaii.htmlAgain..if you do go? the ferry costs are high and so is food. Shop in advance in Terrace or Prince Rupert. Yes, you have to shut off your propane during the crossing. Your fridge will be fine during the crossing. Try not to be in and out of it while in line for the ferry. Let it stay cold.
People on the Island are very proud and quiet...cel service is there in the cities, less so on the road, but if you have trouble, people will stop. Wifi is find-able....you have to be a wee bit sleuthy to find it tho. The weather is cooler than the mainland..and can get wet...hahahha...really wet.
If anyone has any questions? Ask away.
