I have a place about 30 minutes from Disney. My wife and I both have annual Disney pases.
If you're headed down and are not staying at a Disney resort, buy the park hopper passes. If you are staying at a Disney resort, purchase park hopper pass when you check in. They are typically cheaper for guests.
Don't buy for the water park. Use your hotel's pool.
And, above all.....enjoy yourself. It's OK to be a kid again.
