Do you have a favorite restaurant? Do you feel guilty if you decide to eat at another restaurant? My favorite restaurant serves Mexican food. Sometimes I'm just in the mood for seafood, or Italian, or Chinese food or a steak or bar-be-cue. I certainly don't feel guilty for going to another restaurant even though they are in competition with each other. Neither should you feel guilty for going to Universal instead of Disney.
There is lots for your son to do.
Woody Woodpecker Kid Zone
Animal Actors is a is a great show to watch if your son likes animals. Be aware there is one part where a large snake is brought on stage.
The Barney show is another show your son might like. There is also a play area and a meet and greet with Barney.
Curious George is tons of fun for kids of all ages. They can shoot water at others and run though a building with lots of water effects. At the Ball Factory, kids can shoot and throw nerf balls.
Woody's Coaster is a kiddy coaster and was mentioned earlier. ET is also a great ride. Be sure and listen for ET to say your name at the end of the ride.
Fieval's Playland has a slide where kids can take a two person water raft down a small incline.
Production Central
Jimmy Neutron is 3 D simulator ride with stationary seats for younger kids. It features the Nick characters. When you exit, there is an interactive play area and also a meet and greet with Sponge Bob.
Shrek is a 3-D show. There is a meet and greet with Shrek, Fiona, and (my favorite) Donkey. I can spend quite awhile just listening to Donkey interact with the kids.
Suess Landing
The whole land is built for kids. One Fish Two Fish is similar to Dumbo but with water. I'm sure your son will love the Cat in the Hat ride. I'd suggest reading him the book first for even more fun.
If I ran the Zoo is another play area. There are tons of interactive activities there.
The High in the Sky Trolley, takes you on a trolley ride in the sky above Seuss Landing. There are two tracks and four story lines all involving the Sneetches.
You can also meet the Grinch, Cat and the Hat, and Thing 1 and 2.
Jurassic Park
The Discovery Center is an exhibit/museum about dinosaurs. There are games to play to test your dinosaur knowledge. You can create a new dinosaur, or watch some dinosaur eggs hatch.
There is also a sky ride called Pteranodon Flyers where adults can only ride if they are accompanied by a child.
Lost Continent
The Flying Unicorn is a kiddie coaster.
Toon Lagoon
The Me Ship, the Olive is is a stationary boat with stairs to climb, slides, and areas to explore. You can also squirt the people who are on the boats on the Popeye ride.
Marvel Super Hero Island
Storm Force Acceltron is similar to the teacup ride. There are also super heroes who ride on ATV's into Marvel several times a day for Meet and Greet.
Here are the height requirements. All the things I mentioned can be done by your son who is 37 inches.

Don't fear change---change is good.
Not to knitpick Phamton's excellent run down, but just thought I would add in the Jurassic Park area around the Pteradon Flyers is that Camp Jurassic section with caves, water canons, and some other really neat things for younger kids. That is a cool area all the way around. It is very relaxing, has waterfalls etc.
Also, per the earlier discussion, am I the only one on this board that likes the old RP dark red or maroon colored rooms? I liked the colors with the dark wood fixtures that divide the bathroom area from the beds. I thought that was a good color scheme, but oh well.

" schtick?
I posted an innocent comment last year that i thought the room we had at BWV was showing its age and didn't think they were putting the dues money from DVC to full use (paraphrasing) and man did I get blistered
you would have thought i killed somebodies dog (all apologies to any Vick fans 
) Seriously though, i'm a DVC member and I love Disney (love USO too), but can't anyone take any constructive criticism any more
when it happened to me i tried to explain that my vacation was not ruined and i still had a great time and every reply I posted just made it worse, just like you...may i suggest
