We arrived during the first weekend of the off season (November 1st), so everything was probably a lot quieter than usual - with the outdoor pool and beach closed. Yet knowing that the hotel was certainly nowheres near full, we were disappointed to find that our jacuzzi king room (the type of room an adult couple would choose) was next to a room with a family with multiple children. Made even stranger by an adjoining door that would connect the two rooms, and allowed every word, yell, and TV sounds into our room. Obviously hotels have kids, I know that, but I think those room assignments should have been more thoughtful. That adjoining door blocked no sounds was beyond annoying.
I loved the Jacuzzi tub in our room, it was large, clean and worked properly. The tiles had seen better days, but I understand that people are hard on hotel rooms. The bathroom was very small and shabby. The king bed was moderately comfortable. But the room was mostly clean (some dust and hair in the drawer I opted not to put my clothes in). We only ever saw staff at check-in and checkout. The guy at check-in wasn't super friendly, but it was fine. When we were out day-one our towels were refreshed and plastic cups replaced, but the bed was not changed or made.
Next time I'm in the Dells I'll probably pick somewhere else to stay. But Aloha was the cheapest ($150 a night) we could find on short notice with an in-room Jacuzzi, so I'm happy with that.
