The hotels and resorts closest to the board walk might be more $$. My personal opinion Daytona is not what it used to be. but for 1 night or so it should be fine. It is just more for adults.. again this is my personal opinion.
If I might suggest coming a little further south to around Cape Canaveral, you will fine some really great beaches, and more family oriented activity. You could visit the Cape, Ron Jons has a really cool resort complete with water park. I believe that the drive from that area to disney is only about 2 hours or so.
Watch out for the undertoe on this coast. I am a Florida girl ( even though I now live in Georgia just moved 3 weeks ago) and a strong swimmer I'm still very cautious in the water on this coast. Make sure you know what to do if you were to get into it, there are signs posted to help you, and make sure you are near a life guard stand. I'm not trying to worry you, just a lot of people are unaware and don't realize the danger. Again just offering a personal opinion.
