I have been planning for a trip in Oct/Nov for 6, and while I don't have a specific hotel rec, I have some general tips:
1) Do you care if it's one bathroom or two? Wanting two bathrooms shortens the list of possibilities (which can be a good thing, if it's hard for you to choose!), especially if you do not want to roll the dice on getting adjoining rooms as a way to get two bathrooms.
2) Do you want just more beds to sleep six, or do you really want separate rooms? I have found that some hotels call a room a "suite" if there are more than two beds in it, but it can be just one big room. (See Del Sol and BWPPI.) It is important to us to have a place where we can put the kids to bed in a dark room and shut the door while we watch TV, talk, or computer work in a separate lit room.
3) Book early. Lots of the close places have suites, yes, but often they are only a handful, so availability is severely limited. For example, two weeks ago I found out I can't book Park Vue as I intended for Oct 29-Nov 13 because the suites are all booked at different points, esp Veterans' Day. There are only two of those 3-queen suites and only four of the ones with the kitchenette. In other words, just because a hotel offers suites doesn't mean you can get one, especially if the trip is less than six months away. So, going a bit further away for places that are dedicated to suites like Desert Palms or Residence Inn gives you more options because they have so many more suites.
