I want to take DCs to the Harry Potter park at Orlando. I don't know anything really about the Disney parks. Is it best to go through a travel agent but the hotels look so much cheaper booking through sites like booking.com? How to book park tickets? How many parks? How long should we go for? Was thinking about ten days but wouldn't want to spend all that in parks so maybe better not in a park hotel? It all looks so complicated to organize it puts me off. Would be grateful for any advice.
