My elderly parents (75) are going to a relative's quinceanera in Monterrey on 7/25, 26. The party will be at "Salon Los Leones" or something like that on avenida los leones? (They weren't able to give me exact details over the phone, I'll confirm this info once I see the invitation.) I want to reserve a hotel for them that is centrally located so they can walk to the plaza and the mercado but that is also close to where the quinceanera will be. Can anybody help me? Also, if you can provide info on taxis and how an elderly couple can avoid getting ripped off, any tips would be appreciated. Thank you.
