That's great, Kelly!!!! Hope you don't 'suffer' too much in that King sized bed

That's actually a great type of room to have, if there's just the 2 of you. It makes the room seem a little bigger.
If you're truly trying to get a standard room, you can continue to call back periodically.
Edited: forgot to mention this before ---- rates go down on 4/18. Depending on how long you're staying, and if you don't mind taking a small gamble....... keep your eyes open for new codes that start 4/18 and book 2 separate reservations (as I described above). Be sure the CM links them together, and go over this again when you check in.
The gamble is that you might possibly have to change rooms on 4/18, but that really doesn't tend to happen, if the reservations are linked. You would have to pay a separate deposit for the second reservation and might have to check in again on 4/18, but that's just a formality, with new room cards. We've done this and saved some $$$ and had very minimal extra work for the $$$ we saved.
Hope you have a great trip!
