To follow up on my post above, I did inquire about getting an upgrade after the first night of our stay. The hotel was sold out the first night, but there was availability for the remaining 4 nights. They were very accommodating and upgraded us from a Studio Suite to a One Bedroom Suite for the last 4 nights.
This is a very nice hotel. The $50 credit for two people was sufficient to cover breakfast for two. The credit was correctly applied without my having to inquire. My only complaint is that the pool area was very windy. The way it is situated makes it susceptible to the breeze coming in off the ocean. It really wasn't windy on the beach, but it was hard to sit on the pool deck for very long. I suppose that this issue will vary based on the specific weather than you have when you go.
