The Boardwalk area has some neat shops and eateries they could explore.
They could take the bus to the Magic Kingdom, then get on the monorail and tour the monorail resorts.
Do they like tennis or golf? That is an option.
There are Water Mice boats, sail boats, canoes, kayaks, parasailing they could rent at any of the monorail resorts.
Pamper themselves with a massage or spa treatment at the Grand Floridian Spa or Saratoga Springs Spa.
If they like NASCAR, there is the Richard Petty experience. While expensive to ride or drive, it is free to watch others and you are right up close.
If they are considering going on the road someday with a motorhome, they could check out Ft. Wilderness Campground and get some great ideas on rigs.
There are horseback rides at Ft. Wilderness Campground.
If they like to go fishing, there are several fishing excursions on Bay Lake near the monorail resorts.
There are beautiful walking trails around POFQ and PO Riverside
There are two great miniature golf courses at WDW.
If they like baseball the O Rays minor league plays their season games at Wide World of Sports.
Sometimes the Harlem Globetrotters are practicing at Wide World of Sports.
Hope this gives you some ideas.
We'll be at PO FQ the same time you will!! May 21-25!!!!
