I have not stayed at the Embassy Suites South on Harbor, but I also enjoy having a 1-bedroom suite for more space. I stayed at the Residence Inn at the Convention Center in mid-May and it was great. Our room was large, we had a full kitchen w/full size fridge, etc. It's nice to have the extra space and separation between bedroom and living room. They also accept pets, so we brought our dog along. It was walkable but tiring at end of the day.
Today I just booked a 1-bedroom suite at the new Hilton Garden Inn nearby the main entrance since I want something more walkable/nearer the entrance, but still with the space of a 1-bedroom. They only have mini fridges though, so no full kitchen. :/
Haven't tried Homewood Suites yet, but maybe another time!
