My 4 year old son loved this boardwalk. We visit Daytona Beach Shores every year, and my son always asks to visit the boardwalk. They have lots of stores, places to eat, arcades, and activities for kids. They have things like ferris wheels, and a huge bungee jump. This is one of our favorite things about Daytona, but it's a lot of walking so be sure to wear the right shoes and bring a stroller if needed.

We come here every year, and my 4 year old son LOVES this hotel.
It's in South Daytona Beach, away from the teenagers and partying. They have an AMAZING water slide in the pool, and my son adores it. There is a kiddie pool, hot tub, and a lifeguard on duty when the pool is open. There is a cafe on site that serves great breakfast. The hotel has games for the kids throughout the day. It's a few hundred feet from the beach, and the views from the rooms are amazing.
This is a great hotel for children, and I doubt you will be disappointed.

My husband and 4 year old son often buy cheap tickets to catch a Braves Game. It's a bit of walking from Marta to the seats, but my son thinks awesome to watch a baseball game with Daddy. It's their special "thing", and he gets so excited when Daddy tells him they're going.

My 4 year old son LOVES to spend the summer days here at the water fountain. He gets to meet new friends, run in the water, play, and we have a picnic with Varsity chili dogs.
Parking is easy (You have to pay) and there is a high police presence. There is often free concerts in the park, as well.
There are various other attractions nearby - Imagine it! Children's Museum, CNN, etc.
It can become a bit scary at dark, so we make sure to clear out before then.

My 4 year old son loves watching kids movies here. He can be as loud as he wants because it's in the car, and he is not required to behave like he normally would in a regular theater. He usually passes out by the time the second feature is on, so my husband and I can then enjoy the second movie in peace.
The area is kind of rough, so I do not recommended eating in the area. Bring something, or use the concession area at the Drive-In.
