After a while one of your colleagues might offer you a crash pad / take them up on it if you can. It’s good to have a place to stash things and someone to have dinner with or feel like your not staying in a cookie cutter hotel. Repay them with a nice dinner out or offer to pick up or order take out every visit.
Put out feelers with friends and family too. Hotel points are great but this schlep will get spendy over time.
