The original word was that the Royal Pacific would have "family" pricing, around $110-$125/night. Don't know if they've changed that, but given inflation it'll probably be more than that by the time they open, just less than HRH and PBH.
Other. sketchier plans called for two additional hotels towards the Sand Lake Rd end of the property that would be aimed more at the convention center trade. I haven't heard anything on this for a good long while, so maybe these plans have been shelved.
