When researching a place to stay in Yuanyang you'll most likely find Sunny's Guesthouse. Although this is a longer type of review I'll say upfront that Sunny's is a great place to stay for the majority of travelers that pass by this region. The guesthouse offers the most amazing views and they they even have an open air roof that is prime real estate during sunrise. So here is the information that I think will be helpful to anyone traveling through:
When you travel to Yuanyang you'll be dropped off at the bus station in Xin Jie. Sunny's guesthouse will be another 40mins- 1hr trip to 'Duo Yi Shu.' You can either take a taxi and bargain a price (they usually start at 100 RMB) or you can take a minivan shuttle like all the locals do for 15 RMB per person. The shuttle will take you all the way to the observation deck area in Duo Yi Shu. Finding the guesthouse will certainly be difficult to anyone who is just wandering down into the village by themselves so don't be foolish and do so. You're better off waiting for any tourists you see that are walking down in that general direction. Chances are they are staying at Sunny's or right down the road and can help you find it. My point here is don't stay in Xin Jie just because you will be 'far from town.' The smart traveler will pick up a couple days snacks, trail food, toiletries, etc before heading down. (the other thing to keep in mind that the minivan shuttles I mentioned earlier are frequent so you'll have no difficulties catching a ride back to 'town' if you need to. (one specific point I'll make here is if you need a very early shuttle in order to catch transport out of town then you'll need to arrange and hire a driver the day before so they can pick you up first thing.
You can book Sunny's ahead of time on a couple websites, but it is also your best chance in the area to book if you have no plans as Sunny's easily has the most rooms/ room options in Duo Yi Shu. They have dorms, couples rooms with bathroom, couples room without bathrooms. The ensuite rooms for couples have STUNNING VIEWS but there are just a pair of them so you should certainly book in advance and book for your entire stay. The rooms are clean, yet economically sized for sure. Keep in mind the bathroom situation is most likely what the more 'delicate' traveler will have issue with. They are not hyper clean, nor do they always carry tissue, and in general some travelers may pass on the shower and just rough it a couple days. Keep in mind this is the economical option for most, but splurging on the ensuites will be around 180 RMB per night. Just as an example the other room without bathroom is only 100 RMB for 2 per night.
If you are looking to stay in the area and you don't want to have to 'see what happens' and certainly need a bathroom in the room then book ahead and book your entire stay for Jacky's guesthouse right down the road (we stayed at both). Jacky speaks perfect english which is also a huge plus. This does contrast with Sunny's, but there always seemed to be someone around to help translate. All the rooms at Jacky's were 180, but none had the views that Sunny's ensuites provided. I wouldn't get too caught up in the 'view' though because you can walk outside of either just alittle ways and you'll literally be on the rice terraces and can get most any shot you want. Jacky's also has an amazing roof to see out from.
Ultimate lesson - if you want a nice room with a bathroom book ahead and book your entire stay online. We found many couples including ourselves bouncing between both guesthouses just to find a place to sleep.
The other thing you'll read about is 'price gouging' for the meals served. Keep in mind both places serve breakfast, lunch and dinner. The dinner at either on any given night is certainly worth the money. For lunches, and other meals my biggest suggestion would be to buy some of the noodle bowls from town before you even take off for Duo Yi Shu. Just grab enough for a couple days worth (shouldn't add much to the load) and then you won't have to worry about meals. If you get there without any rations then the meals may seem expensive as they are not a-la-cart.
On a final note before I end the sunrise in Duo Yi Shu is simply amazing. The sunset is pretty damn good too. Staying in this area is great, and it won't make you have to get up any earlier than necessary to just walk outside your door and see some of the most fantastic views you'll ever see in your life. You can easily hire a driver for the day to take you on a tour of the other locations around the area.
