I will say the Inn On Lake Superior has been and is our place to stay. I usually make a reservation by phone. I recently did so getting a room for the Christmas Bentleyville lights coming up. I was quoted a price, but we did upgrade to the lake side view. Was told the Bentleyville discount was cheaper than the AARP discount. I did book the room. While playing on their webpage I was just checking out the fireplace room and noticed the same room we had booked was about 20.00 cheaper using the AARP discount ! I did cancel and take the cheaper room price of course.
When I called the hotel and asked how this happens, it appears the direct hotel reservation prices are different than the do it yourself reservations on line. This happened to me recently with another hotel. The person on the hotel reservation phone line told me straight out that we pay for them to make the reservation, and it is cheaper to do it yourself on line ! I guess I should have paid attention. Is it this way all over ? Not sure, but worth checking out. Just a heads up !
