[QUAD-L] Accessible Hotel Chains

[Don Price]

Just wondering if any of you travellers have found national hotel chains that 
consistantly provide good or excellent wheelchair-accessible rooms (including 
roll-in showers.)
 
Affordability is a factor for most of us, so preferably the low to mid-range 
chains.
 
I apologize if this has already been discussed, but I missed it.
 
Thanks in advance,
Don.
