I used mousesavers to check for deals, tips, tricks, and how to find the best deal. I used AllEars for seeking out planning information, as well as tips & tricks for the parks, dining plan, hotels, etc. I checked the WDW Vacation Planning site to check for deals.
I ended up booking a package deal through Disney. I had a special deal through my Disney Rewards Visa that I took advantage of for booking the trip.
If you are going to book each part separately, I suggest using one of the great MC Sponsors: Orlando Fun Tickets. I have only heard great things about them.
Hey Mamabot....you forgot us, we're sponsors too. You gave them very good advice. If they do everything separate then they should go to Orlando Fun Tickets for their passes. They will give them a good deal & take good care of them...
