Feasible to get Taxi from Osaka Station to APA Umeda Eki Resort?

We will be landing around 7pm at night, and plan to take the Haruka to Osaka station. Is it feasible to catch a taxi from Osaka Station to Apa Umeda Eki resort, as it's saying it's an 11 minute walk and we will have kids with us. I read somewhere that it could take just as long to walk to the right exit and find a taxi as it is to walk there, is this true? Thank you.
