I know this isn't a huge help - but HRH had boiled eggs at breakfast every day in the lounge. It would be weird if it was only 2 out of the 3 hotels that had them; hopefully someone will be along that can confirm.
I will say they were great at getting us stuff they had that wasn't out all the time: for example, they had peanut butter packets out at breakfast for the toast and they would get some for DD each evening so she could use it with the raw veggies that were out with the appetizers.
