I'm retired on social security and my sister is handicap so when I walked in I ask for a double bed down stairs she said her there was 2 rooms so she got everything senor discount and had everything she wanted a credit card I don't care cards so I had a debt card a and she said that wasn't good it had to be a credit card so I told her I call the motel 6 corporate office and talked with 2 people who then keep passing the buck i'm very upset because I have been going to motel 6 for a very long time and now this women in blythe was rude and refused us and we ended up sleeping in our vehicle because all the rest were full I will never go back and stay a that or any motel 6 again and the people and family as well will not stay. You need to have the same rules and regulations for all motel. Sincerely lori camp
