Just keep in mind the honey bees will take the sugar watewr and make some use of it till it get down to the 50F mark. Once it gets there they will still be flying on sunny days but will not touch the syrup.
Also keep in mind with the open feeding station they will be competting with the wasp (yellow jackets) plus you will have the yellow jackets in the area till it gets cold and they all die except the queens.
