I thought the same thing but I was pleasantly surprised. I figured it would be like having 2 rooms at a value but it was much better. Having a living room that converts into a bed room for the kids and a private bed room for mom and dad with a queen size bed was a big plus over just having 2 rooms. The kitchen is not much but it is just enough to do a quick breakfast or warm up leftovers which again is a big plus.I don't think it's much from what i seen on a video. I was going to get that but after i saw that i was like ohh nooo.
You are correct 2 rooms are less expensive. The suites are currently in preferred room locations and typically price out slightly more expensive than 2 preferred rooms. In terms of expense they rate third for accommodating a party of 5 and second for a party of 6. Also due to very limited availability they are rarely discounted. It will be interesting to see how they price out when Art of Animation opens up.
