We stayed at Residence Inn Seaworld in July 2004. We had a 1 bedroom suite for about $114 a nite I think, got that from the 800 number, I think!
It was 2 queen beds and sofabed in living room, sofabed would be good for 2 small kids. It had full frig, stovetop, microwave, dishwasher and all the plates and cups and stuff. The best thing is the full American breakfast.
Scrambled eggs every day(a little bland)sausage pattys one day and ham slices the next, several cereals, muffins, waffles, fruit, something for everyone. To me that's worth about $10 per person, and it's free. I would go down and get a platefull and take it back to the room, that way my DD stayed in bed a little longer!
Have a great time!
