Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE party_host ( party_id number, host_id number, is_main_in_charge others )
TABLE: CREATE TABLE party ( party_id number, party_theme text, location text, first_year text, last_year text, number_of_hosts number )
TABLE: CREATE TABLE host ( host_id number, name text, nationality text, age text )

### Question ###
Show the locations of parties with hosts older than 50.

### Accurate SQL ###

SELECT T3.location FROM party_host AS T1 JOIN host AS T2 ON T1.host_id = T2.host_id JOIN party AS T3 ON T1.party_id = T3.party_id WHERE T2.age > 50
