I love Coronado Springs! I would stay there everytime I go to WDW. It is a beautiful resort! We never had any major bus problems or any problems for that matter. The main pool is awesome. I would recommend staying in 8A Cabanas. We always ask for this area or even a room number and we usually get it or close to it. I can't find the room number right now if I do I will let you know. We like the rooms on the second floor with the double window. This location is close walking distance to the main pool and not a far walk from bus stop 4. It is all the way across from the pepper market (where the food, games, shops, bike rentals etc. are) If you don't want to walk over to it you could take a bus to bus stop 1 (there should be a sign at the bus stop that tells you this or which bus to take. Someone please correct me if I am wrong). Most of the buses start returning guests starting with bus stop number 2.
I would pick CS over CBR and I have stayed at CBR 2 times and Coronado several times (see my signature). The bus service at CBR was slower to us. The main arcade in CS however is on the smaller side. I am comparing it to the Contemporary Resort as it is the only other one I have been in and can remember. I would get a bus to MK and ride the monorail to the Contemporary to play in the arcade. But this was last year before the arcade was remodeled and moved. Anyways there is another smaller arcade right near the main pool area. I think it is called the iguana arcade. There is also a playground right near the pool. Also the pool bar is nice for the adults and you get food there like chicken fingers and fries. I know you are looking for the better arcade but I would highly recommend staying at Corornado Springs. If you have any questions PM me I have alot of info to offer about the resort or WDW for that matter.
