I hope I can help you begin to sort it out.
My first suggestion is to always look at which resorts are scheduled for renovations.
So, let's cross off All Star Sports (until mid-May) and Caribbean Beach because their pools will be going through renovations during your visit. The Coronado Springs Resort’s Jaguar pool slide will be closed although the pool will remain open. Exclude this option if anyone traveling in your family would miss having the slide.
Depending on your party size and ages, I would recommend
Pop Century for a value resort. It does not share bus transportation with other resorts. It is also the newest of your 4 choices in this category. However if you have a small child that loves Toy Story or 101 Dalmatians for example, then you must head to the All Star Movies. Our son loved Herbie the Love Bug and he truly enjoyed waking up at that resort to greet Herbie each morning.
For a moderate, I would recommend
Port Orleans French Quarter. It is a smaller quaint resort with a nice food court, one bus stop (although it shares with Port Orleans Riverside) and has boat transportation to Downtown Disney. If you will have your own vehicle, we found the parking lot very convenient to most buildings. The pool is nice although the slide appeals to younger children.
If this doesn't help, write us back and let us know how many are traveling in your party. It also helps to know if there are kids with you and their ages. I hope this helps you to start narrowing your choices.
Best wishes!
