I wouldn't trust the chat. Whenever I make a room request, I always call about 4-5 days out, give them my confirmation number and ask them to read back to me any room requests. Every time I have called in my request they have correctly read it back to me. Out of curiosity I used chat, on 3 separate trips, to enter room requests and each time I called to have them read back my room requests they said there were none.
