Thanks to welcoming man at check-in were able to access our rooms couple hrs early and enjoy much-needed naps. Early to mid-evening my travel companion & i fully immersed ourselves in a pretty blissful relaxation found no where else in Mackinaw City thx to the Riviera's uninterrupted expansive views of the entire straights. Ofc the Bridge.., and the steady, pleasant appearance & reappearance of the island ferries, ..., but we were most fortunate to catch 3 large freighters traversing between L. Michigan & L. Huron. All of the above paired w/ the unmistakable sounds found at the tip of the mitt..., waves gently hitting the shore, the deep baritone horns of the freighters and the shifting of the big rigs into lower gears as they climbed initial spans of the iconic bridge. The last of those even hit just right thanks to perfect mix of blue skys, clouds and off-shore breeze. All of this eclipsed by nothing more than the perfectly clean, comfortable and wonderfully! "up-North" themed guestrooms of the Riviera.
