I always email my requests, I give them 5 or 6 room numbers. I also send a touring plans. I leave online checkin requests blank. I’ve been fairly successful, got a nice park view earlier this month at VGC. Didn’t work at BLT in September, I had put down room numbers on 8 and 9 facing MK (lake view), they gave me 2nd floor, which was barely a lake view. I went to the desk and they moved me to the lake side on the 9th floor, it was beautiful.
