Other than the Renaissance, I believe that the closest (and the easiest walk) is the Hilton Garden Inn. Further up Westwood Blvd. closer to the convention center area but walkable are a Sleep Inn, a Hawthorn Suites, and an Extended Stay - I think that there was another one over there but it looked closed when I drove by in late Feb/early March this year. And further down Westwood Blvd. in the opposite direction are a Residence Inn, and three timeshare properties - Hilton Grand Vacation Club SeaWorld , Marriott's Cypress Harbour and Marriott's Harbour Lake.
