Dear Gutto,
My Sister-in-law is from Brazil! I hope you have a wonderful time here!
To answer your question, my family loved CSME. We stayed there twice, once in 2000 and once in 2001. My kids thought that the best part was the free continental breakfast. They had waffles, pancakes, fruit, yogurt, donuts, muffins, cinnamon roles, bagels, cold cereal, oatmeal, grits, coffee, tea, hot chocolate mix, orange juice, and apple juice. The friendly staff made sure that food was in abundance. The dining area was large and you could also go a few steps out a door and eat by the swimming pool.
The pool was clean and heated, although not large. However, it was never crowded. There was also a children's wading pool with a mushroom fountain.
Beyond the pool in the back of the hotel, is a forested area where we saw a number of deer. The front faces Old Town where you can watch bungie jumpers take the plunge. So the view is pleasant and fun from any room. We did not walk around Old Town much, we just ran out of time. So I can't tell much about that. However, it seemed to be a very casual place, not fancy.
Publix grocery store is very, very close along with many restaurants.
The only problem was when we stayed the second time at CSME, our room was over the hotel laundry. It sounded like we were sitting on a jet engine. I just told the hotel clerk that we would like another room and she was very quick to offer us another room on the 7th floor.
The rooms are very clean and roomy. Ours could sleep six. It had two queen sized beds and a pull out sofa bed. It was called a suite, but the bedroom is not closed off from the sitting area and bathroom. It is only separated by a partial divider. It had a microwave and a small refrigerator and sink area.
I believe the hotel provides a shuttle to DW and some of the other parks. I'm not sure how good it is, because we rented a car.
CSME is also very close the Disney planned community, Celebration. We really enjoyed walking around here. It's fascinating. There were also some very good restaurants, shops and a movie theater here. My family toured a million dollar home that was for sale in Celebration. It was fun!
Hope this helps. I don't know the age of your kids, but I probably wouldn't let them wander on their own around Old Town unless they are much older. Yes, you can walk to the shops safely. They are only a short distance from the hotel.
We'll see if the staff has remaind as nice when we go in October. I hope they haven't become rude.
Have a good trip.
