RV trailer or motorhome? If a trailer, do you have a tow vehicle that will handle it? Motorhome? Check the rental cost, fuel costsof diesel or gas (this will be a big expense as you won't get the mileage of the family car or van; 5-8 mpg if lucky), insurance under your own policy, etc. and compare with a motel room. Think how everyone will abe if you are stuck inside during bad weather (personal experience- almost to the point of mass murder). I met a renter once- all he did was fix the rental RV. Had the greywater tank come off in the middle of the interstate! Also, you will have to cook, clean, etc. just like at home. My parents had four motorhomes and friend who had a houseboat. Keeping two houses. Personally, I wouldn't have an RV of any kind unless I was able to travel at least 6 months out of the year.
I got rooms for conferences in NH and OR and got my best rates with Hotwire. Get one with a decent breakfast. Many now offer a full breakfast- take that into account of what a restaurant would cost per person and compare it with the motel offering and rate. Used to travel in sales for over 30 years. Could write a book on travel. Sorry if I seem negative but this has been my observation for about 35 years. Seriously, for just one week, consider another way, IMHO.
Let me add- when the wife and I travel, we make sure the room has a microwave if there is nothing furnished by the motel. You can get all kinds of stuff at the grocery for breakfast. Eat a light lunch and go to a nice restaurant for dinner. Surprising how you can save $$$ this way.
