Is it a complimentary breakfast or do you pay extra?
If you are not a Hilton Honors Gold member, then it costs extra. I believe it was about $11-$12. But it was quite good.
If you are a Diamond Hilton Honors member the breakfast is free for 2 people.
We didn't eat the breakfast, but I'm pretty sure it was extra.
The breakfast is extra unless you are staying on a bed and breakfast package. It is 9.99 per person. But it is a cooked to order breakfast with wonderful baked goods available, as well as fruit, oatmeal, etc.
