We've stayed at both and I like the location of Horizon better. Stonebridge is a long ways from town and Horizon is in town. Also, I think that the studio at Horizon would be the lock off portion, is that correct? I think it had a little space with mini refrig. and microwave, but I don't remember if it had a cooking burner. Can't remember exactly, as our friends were in that unit of our two bedroom and I didn't pay too much attention to what the cooking facilities there were. I think it was a little smaller that the small side of Stonebridge, tho. Both are lovely resorts. We have a 2 bed room week booked the first of June at the Welk Resort and we're excited to see that one. However, my husband has been having some health problems so might not be able to go.
