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 dorm_amenity (amenid VARCHAR)
TABLE: CREATE TABLE lives_in (stuid VARCHAR, dormid VARCHAR)
TABLE: CREATE TABLE dorm (dormid VARCHAR)
TABLE: CREATE TABLE student (fname VARCHAR, stuid VARCHAR)
TABLE: CREATE TABLE has_amenity (dormid VARCHAR, amenid VARCHAR)

### Question ###
Find the first name of students who are living in the dorm that has most number of amenities.

### Accurate SQL ###

SELECT T1.fname FROM student AS T1 JOIN lives_in AS T2 ON T1.stuid = T2.stuid WHERE T2.dormid IN (SELECT T2.dormid FROM dorm AS T3 JOIN has_amenity AS T4 ON T3.dormid = T4.dormid JOIN dorm_amenity AS T5 ON T4.amenid = T5.amenid GROUP BY T3.dormid ORDER BY COUNT(*) DESC LIMIT 1)
