I regret booking at the Watermark Inn. I felt ripped off. You can do much, much better elsewhere in Ptown. I paid $300/night off-season. My friends stayed elsewhere for under $200 and had nicer accommodations. I didn't mind booking a more expensive place, because I wanted a luxurious experience, but the Watermark Inn was a bad decision. The waterfront location is nice BUT...
-The interior is super-cheap. My king bed consisted of a couple of twin bed frames pushed together, with the mattress overhanging the frames by a foot.
-towels are paper thin, dishes by IKEA, old berber carpet, cracked tile in kitchen area, super-tiny refrigerator had a bad odor, TV was small Dynex (cheap brand) without sound on many of the stations.
-No A/C so the place is always damp and too warm during the day.
-Rusted out heaters left behind a residue of rust flakes/droppings on the floor.
-The 'private' sun decks are not private at all. There is not a privacy divider so you will essentially share the deck with your neighbors.
