We did not go to a basketball game. Other places we visited:
1) Dezerland - a huge renovated mall with literally thousands of antique cars, bicycles, motorcycles, vehicles from movies, a special exhibit of 007 cars and memorabilia. Well worth the entrance fee. Clean, with restrooms. Other areas have activities for families and food courts too. Located on International Drive.
2) Gatorland - short drive from Orlando. Lots of alligators, parrots, unusual animals, and a budgie room that you walk into, buy seed sticks and experience the birds eating seeds while you hold the sticks. Walkways are above the gator areas. Safe and clean.
3) Baseball games- Spring training in several locations. Buy tickets ahead of time.
4) Disney Springs area - lots of opportunities to purchase Disney stuff and eat at restaurants and bars. Hollywood Orlando has memorabilia on all walls plus a huge video on the overhead dome. Quite loud - shouting was the only way to communicate with your table friends.
