You did not say adult or kids or both. Also, I have a hard time with budget friendly since that could mean many different things to many different people. So I will list things and you take it to your budget.
POR and I believe FWL have pole fishing, it is like $3. Those two resorts also have carriage rides for like $45 and 4 or 5 people can fit into a carriage. Trails end is so good breakfast, lunch or dinner, with one of the other activities is great. fWL also has many many activities, camp fire with chip and dale, then a movie. Archery about $20 a person. The barns and ponies and horses are all great. Expensive for a large group would be the horse back riding, $45 a person but less expensive would be a wagon ride, I think $6 a person.
One thing now at BC if you have children, I believe you can go into sandcastle daycare, sorry can’t leave children but they can go in with parents from I think 1to 3 and play and enjoy the club.
If you have kids or just like to collect things, ride all kinds of tranportation, they give out collectible cards on buses, ferries and monorails, try to collect them all. Stop and see several lobbies and look for tours at some of them, BWI use to have a tour at about 9:30 around the board walk. WL has a tour of the lodge I think around 3. AKL probably has one as well.
Take a walk to find things, or rent bikes. They probably don’t have the special right now at WL but maybe at another place that is under construction may, but when WL was under construction for more than a year, you could just take a bike, we took one and went thru the path from WL to FWL, saw lots of things, stopped to figure out the old water park that use to be there, saw the enterence. Then went around the barns and took the bus to the middle of the fort and walked around the store. Took two hours of fun family time of getting to connect again and laugh at mom and dad riding bikes.
Go to POR and POFQ and walk around, take a boat ride to down town Disney, take a moment to grab a beignet.
Go to AKL and out on the ledge to see animals on the savanna.
As other say water crafts are at most hotels.
Grab an ice cream at beaches and cream or better yet grab a kitchen sink and laugh over it with 10 spoons.
Go to mini golf, about $12 a person, my have coupons that time of year, we use to get some for before 4pm around jan.
Take a walk thru down town Disney or Disney springs.
Is Disney quest still open, that is fun for kids, and quite different from the theme parks, but again expense, probably more than $25 a person.
Hit up TRex, totally different experience for eating.
I’m sure there is more, but that’s all I can think of.
