The staff was very friendly and accommodating. The room was clean and spacious, but not very easy to rest and relax and we were on the 2nd floor, directly above the lobby. It was so loud in the lobby and near the elevators until almost midnight. The pool was so overcrowded that they had to shut it down for maintenance, water was still murky when we’re finally allowed in. The staff seemed overwhelmed at that point. Maybe the clientele is different during the week but the majority were incredibly loud and obnoxious during our weekend stay. The complimentary happy hour and hot breakfast are lovely, but so many guests were trying to scam the staff and ruin a good thing. Given that there is now security (at least a staff member wearing a security shirt) and there is a behavior policy you need to sign off on, I assume there’s been a lot of sketchy behavior recently like a lot of places in OakBrook. Would be willing to try again during the week as the hotel is beautiful, but not entirely sure I’d book again. If looking for a nice indoor pool, I’d definitely avoid. It was in great need of regular maintenance.
