We really loved OPR. In fact, DH said he would never stay at POP again, and my parents are already planning a trip back for later this year (this was their first trip to WDW) and are planning to stay at CBR, even though I suggested that they could stay at a deluxe...they said they liked CBR so much that they want to stay there again.
I had requested a room with a king sized bed for them, and also had requested Jamaica 45 or Aruba 51 (or is it Aruba 45 and Jamaica 51? LOL)....but we ended up in Barbados 14, and my parents' room did not have two king sized beds. I asked my Dad at check in if he wanted me to talk to the CM about it but he said they would be fine with two double beds so we just left it. I didn't ask at check-in to see if they could move us to Jamaica or Aruba. Honestly, we ended up really liking Barbados. There were a lot of empty rooms so it was very quiet. We had a corner room, parking lot view, but there were so many trees and plants blocking most of the parking lot view that we couldn't really see it. We were on the 2nd floor. The walk to OPR was not bad at all -- it was quite lovely in the evening and at night, and the bus stop was very close to our building.
We arrived at about 9 pm and check-in went very smoothly and quickly. I had not done online check-in. They got us checked in right away -- no waiting.
Housekeeping was pretty good. We had towel animals two days. My only complaint was that they didn't leave soap and shampoo on our last few days and I had to ask for them. One funny thing with housekeeping -- our DDs brought pillows from home, and I hadn't thought about the color of the pillow cases. One of them had a white pillow case on her pillow, and the first morning she left the pillow on her bed. So housekeeping assumed, I guess, that it was a hotel pillow and they put a fresh pillow case on it. I feel bad that they ended up with one of our pillow cases, which was definitely not as nice as their pillow case that we brought home with us.

I called the front desk about it and they said not to worry about it.
We watched the IllumiNations fireworks from the beach at Martinique and from OPR a couple of times. It was a nice view.
We ate at OPR more than I had planned on. We had breakfast there on Sunday and everyone liked it (Mickey waffles, fruit cups, french toast, eggs, etc.). DH and the girls had pizza and said it was good pizza, and I had a chicken caesar salad and it was good and fresh (made right when I ordered it). One night I ordered the Greek salad and it was awful...too much dressing, and the dressing was too strong, so I ended up not eating that. The roast turkey was very good, according to DD14, and DD10 and I liked the rotisserie chicken. And of course the chocolate croissants were yummy in the morning.
We all liked the pirate pool and were surprised that it really didn't get very crowded. I didn't remember the second hot tub until our last night there...the hot tub on the front side of the pool was completely full and I decided to walk around to take some pictures and found the second hot tub, which was totally empty, so DH and I hung out there for a little while. We actually swam more at the quiet pool in our village because the girls said the water was colder in the quiet pool, there were fewer people, it was deeper water, and it was closer to our room.
We saw lots of wildlife -- ducks, bunnies, various birds, turtles in the bay, lizards everywhere, and even a small snake.
The beaches were nice and usually not crowded at all. Loved the hammocks in the evening.
For the most part, we had no problems with the buses. I can only think of one time we had to wait 20 minutes for a bus, and that was to DTD on Sunday afternoon. A CM at the bus stop noticed that we had been waiting for a while and called to check on the bus for us. We only had to stand on a bus once, and that was on Friday heading to DHS in the morning (I had forgotten it was morning EMH there so I couldn't figure out why the bus was so crowded, LOL). We also had good luck with the buses going back to the hotel every evening. We drove ourselves to MK one morning (we had an 8 am BBB appointment), to AK one morning (the AK bus had just gone by and we didn't want to wait for another one)...I drove myself to DHS one afternoon for a DISmeet (was running late and didn't want to have to wait for a bus). Yesterday, we drove ourselves to BB and DTD instead of taking the bus -- DH and the girls wanted to sleep a bit later than we would have been able to if we had taken the bus. All in all, though, we were very pleased with the bus service. There were a few times that we were the only people on the bus and the bus driver skipped the other stops to take us directly to our stop. That was nice.
We are so happy we chose CBR, and I really appreciate all of the helpful information everyone here provided. We can't wait to go back! In fact, since we went on the special military tickets, we have 3 water park entrances left and we're thinking about doing a water park weekend in October...if so, we'll definitely be staying at CBR again!
I'd be happy to answer any questions!
