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 Rooms ( roomName VARCHAR, RoomId VARCHAR )
TABLE: CREATE TABLE Reservations ( Rate VARCHAR, CheckIn VARCHAR, CheckOut VARCHAR, Room VARCHAR )

### Question ###
Which room has the highest rate? List the room's full name, rate, check in and check out date.

### Accurate SQL ###

SELECT T2.roomName, T1.Rate, T1.CheckIn, T1.CheckOut FROM Reservations AS T1 JOIN Rooms AS T2 ON T1.Room = T2.RoomId GROUP BY T1.Room ORDER BY T1.Rate DESC LIMIT 1
