There are some obvious Loos available to those with disabilities and those without disablities, which many folks forget about.
Crematoriums have disabled facilities, I checked a few locations and they aren`t listed, ALL should have disabled facilities available, most will not be in-town and maybe just outside so well worth checking beforehand - most will likely only be office hours - I guess most wouldn`t think of these, but as they sometimes "needs must" and generally the facilities are clean and checked throughout the day.
