We have cereals like rice chex ahd cherios and juices and whole fruit which I think are gluten free. I think we may have some other items, but you can best determine if they are suitable.
I will go to the web site only to check the going rate and then use other 3rd party sites as priceline, hotels, hotwire and Trivago (which compares multiple sites at once) for the price comparison. I have heard that if you call the hotel directly you can usually get a better rate if you tell them the rates you found, but have not done that myself. If you are a member of the hotels rewards program, they will inform you of any promotions or deals going on.
