where to stay w sister and nephew in 2020

thinking of trying this next yr in late feb or early March..May ..trying to avoid spring breaks but like Flower and Garden. ive been to WDW about 30 times. sister hasnt been for a looong time and i havent been to wdw with her since we were younger. nephew is in early 20s. sister wont go on fast rides, small world is her speed and sitting by the pool. ive stayed at almost all of the resorts. i checked into renting pts which ive done before but looks like $2500 for OKW, AKL for 5 nights for a room w 3 beds, sofas..AOA is a possibility. i would love WL but its pricey. i didnt really like BC other than the location as Epcot is my fav. POFQ and CSR are my fac moderates, WL is my fav deluxe. any thoughts on places.
