OH MAN. I have a game I like to play Planes, Trains, Boats, and Automobiles. My wife and I do this sometimes.
When we resort hop, we try to ride as many different types of Disney transportation as we can in one day. Usually, we get close to getting them all, but the "planes" part only works if it's the first or last day of the trip.
Here's an example. We park at GF. We ride the monorail, exploring the resorts. We take the monorail to the MK entrance, then ride a boat to WL. If we started REALLY EARLY in the day, we might then ride the boat to Fort Wilderness. Either way, we take a bus to Disney Springs. From there, you can do whatever, but when you're ready to move on, you take a boat to Port Orleans French Quarter. Now we like to walk, so we'll trek down to Riverside. Lunch is a good option either at DS, POFQ or PORS.
*Here's the part of the trip where pending time, you can explore some of the resorts that are more isolated (I'm looking at you AK Lodge, Coronado Springs, Caribbean beach, etc.) If you have any interest in those resorts, the best way to get there on Disney transport is to take the first bus Epcot or MK bus that comes at Port Orleans and then take a bus back to the respective resort.
We then take a bus to DHS. We take the friendship boat down to the "Swolphin" area and hoof it around the Boardwalk, Yacht & Beach. There are tons of dinner options on the Boardwalk loop, but unfortunately, quick service is lacking. You've got the pizza window and the little burger cart, but I recommend splurging a bit at the Crew's Cup. The Crew's Cup is a bar connected to the Yachtsman steakhouse. They serve what I consider to be the best bar menu at WDW, consisting of food made in the kitchen of the Yachtsman. Two words: truffle fries. Hopefully, it's early enough that you aren't getting caught up in the folks waiting for their table at The Yachtsman. If that's not interesting to you, see if you can make an ADR at Beaches and Creme. Now here's where the path gets interesting. If you're a passholder like us, you can walk through Epcot and take the Monorail back to WDW. This option also allows you to eat inside of Epcot. I am assuming you do not have this luxury. If you're not going to enter parks at all, you gotta bus is back to the Kingdom, then you can ride the boat (or monorail if you're sick of boats) back to the GF.
If you do all of that, you should have ridden on 4-5 different types of boats, the buses, and the monorail.
