SELECT random records from two tables

I have 2 source tables employees, locations, which don't have the same record counts and a destination table access_history.

I want to randomly pick records (some columns from each table) and populate my destination table with those values.

I know I can do a subquery (see below) to populate the employee part of the access_history table.

INSERT into table access_history
SELECT 
from ( select employee_id, 
                     card_num 
                    from employees 
                    where 
                      last_name like '%' 
        order by dbms_random.value  ) 
      where rownum <= 2

I have 2 questions, how can I populate the locations part of the access_history table with random values.

Secondly, how can I populate access_date column with random but meaningful DATETIME values? Meaningful being a hierarchy of dates where the second date is greater than the first date by 10 minutes- 5 hours, the third date greater than the second date by the same criteria and so on and so for each record per random employee_id.

Lastly, this is ONLY test data and I'm not worried about performance issues as I know there is overhead with DBMS_RANDOM. My goal is to wrap this in a connect by level <= 10000 statement so I can generate plenty of test data.

Thanks in advance to all who answer.

My data should look something like this:

SELECT * from access_history 
ORDER BY employee_id, access_date 

1, 'AAA1', 101,  '06212020 21:02:04', 0
1, 'AAA1', 102,  '06212020 21:22:54', 0
1, 'AAA1', 104,  06222020 01:13:11', 0
1, 'AAA1', 101,  '06212020 05:29:22', 0

3, 'CCC3', 105,  '06212020 08:42:34',0,
3 'CCC3', 102,  '06212020 16:09:55', 0
3 'CCC3', 104,  '06212020 22:29:53', 0

  Insert into locations values (102, 'South Front Door 2', 'T');

  Insert into locations values (103, 'East Back Door 1', 'T');

   Insert into locations values (104, 'East Back Door 2', 'T');

   Insert into locations values (105,'Computer Room', 'A');

   Insert into locations values (106,'1st Floor North',  'A');
