CBR room request?

My DA has already requested Martinique for our October 15-20 stay - would it be beneficial to send a fax request for a certain building or would that be overkill

I just requested Martinique. TP sent a fax, I requested it during online check in and requested over the phone with a CM. Didn’t get too specific just Martinique 2nd floor - noted that on the TP fax too since it does get specific. Got a wonderful 2nd floor corner room in Martinique!!
