We tried to upgrade to HRH concierge last year, but they were booked. So, I do not speak from personal experience, but we were trying to upgrade on the recommedation of a friend (with 3 growing boys) who felt that it was worth it money-wise because of the food offerings for the kids.
I think because all three properties are operated by Lowe's hotels, the concierge should be very nice for all hotels.
