Hi! Good question!
1. If you go in late September/early October, there really aren't that many kids at all. When we made our trip there in September 2000, we saw many more couples than kids - couples honeymooning, celebrating anniversaries, etc. It really changed the atmosphere.
2. The kids aren't that bad, usually. Unfortunately, for our Disney wedding & honeymoon, we had to go in August, since I'm now a teacher. Yes, there were kids, but they really weren't bothersome (though I will admit I got irked by all of the bathing suit-clad, barefoot kids running through the hallowed lobby of the GF
And if you dine around 8 or 8:30, at the pricier restaurants, you still get that same mostly adult atmosphere. Yes, we had one evening in Bistro de Paris where a baby wouldn't stop screaming, and his mother (who was wearing pants and a bikini top) wouldn't take him outside. But that is the only time I can remember being truly annoyed at dinner.
3. The atmosphere - despite all the kids, this is absolutely the most romantic place we've ever been to. Where else can you have dinner in a restaurant on a lake, watching a castle change colors? Or see fireworks start exploding over that lake, while the lights in the restaurant dim and When You Wish Upon a Star starts piping through the room? Where else can you go parasailing, golfing, get a massage, get married, go on a safari, eat lunch inside a castle, dance in the beautiful lobby of your hotel to an orchestra, and dine in a restaurant as elegant and delicious as Victoria & Albert's? I think the beauty of Disney is that it can be anything to anyone. It can be that pampered, relaxing vacation. It can be educational, as you explore the exhibits of Future World. It can be exotic, when you watch a giraffe wander past the balcony of your hotel. It can be elegant and romantic, with the castle and the Grand Floridian. It can be rustic, like the Wilderness Lodge. And the best thing is that you can have all that in one single vacation!
4. People are just nicer at WDW. It's true! When we looked around, almost everyone was smiling. People stopped to ask us if we wanted them to take our picture together. Heck, we stopped couples to ask them if they wanted us to take their picture together! On 2 occasions, guests at other tables sent drinks over to us, because we were on our honeymoon. It really is amazing, and the best part is that the guests' happiness means they reach out to other guests in a friendly way, instead of being self-absorbed but happy.
5. You're a prince and princess for as long as you're honeymooning there. We wore the wedding ears, and got the royal treatment from EVERYONE! In fact, we wrote a thank-you letter to Disney afterwards, and had to include the names of 28 different cast members who helped make our trip magical. If you honeymoon at Sandals, you're just one of many, since basically everyone there is a couple celebrating some romantic occasion. At Disney, people talk to you about your wedding, and if you are as lucky as we are and got married at Disney, they are amazed. At so many different rides, we were given our own row, or bumped to the front of the line, or publicly congratulated by the cast member there. At restaurants, we got free drinks because everyone seemed genuinely excited to see us there for our honeymoon.
We never thought once about going on any other kind of honeymoon, or about being married anywhere else. Disney is so special for us, that it would take a lot to even dampen our excitement, and the super-abundance of kids is really a very, very small part of the big picture.
Cheers!
