Going in July it will be HOT with rain showers many days. The skyliner will shut down during times of lightening and it can be a very long wait for Disney to get the buses going for the affected resorts. (Pop, AoA, CBR and Riv) CBR is also a very large, spread out resort with lots of walking and minimal shade during those treks. Staying 9 days, your feet will already be quite tired from all of the walking in the parks. I would not stay at CBR during July for these reasons.
AKL is a beautiful resort and all of your walking would be indoors. It is however very isolated and a bit far from everything except AK park. 9 days at AKL would get a bit monotonous. I would choose to just visit AKL for a meal on your trip.
WL is a beautiful resort and very close to MK. Not sure of the makeup of your traveling party but if small children are involved, this would be ideal as it's only a boat ride away from MK. You can also boat over to FW and CR. Getting to CR also gives you access to Poly and GF for dining and shopping via monorail. WL is great if you are spending a lot of time in MK but not so convenient if you are spending lots of time at EP and DHS.
POR and POFQ are a great compromise of price, location, and theme. These resorts are pretty well located for a quick ride to the parks (except AK) and a relaxing boat ride to DS. DS gives you LOTS of dining and shopping options. POR is a larger resort but it has a lot of shade trees which aid in summer walking outdoors. POFQ is very compact and would be a nice break for your tired feet after long days in the parks. POR has several bus stops which will increase transit time to the parks. POFQ has a single bus stop at the front of the resort so buses will leave and go directly to the parks. POR has a really nice main pool and several smaller quiet pools. POFQ only has one pool. If you have small children, POFQ has a nice pool, water play area and playground all in the same vicinity. Because POR and POFQ are sister resorts, you are welcome to use the pools and amenities at both if you so choose.
Our family of 4 adults chooses to stay at POFQ because it is easier on the budget (we do 2 rooms), it is very compact, theming is so quaint, the food is outstanding, and the bus and boat transportation is efficient. I would also add that we have found the rooms to be very quiet. Although the pool area is a bit juvenile, we didn't care as we don't utilize the pool very much in Jan/Feb which is our new preferred time of year now that our adult daughters are out of school. When our daughters were young and we only reserved one room, we preferred to stay at Poly and GF.
