I did online check in for my stay next week, because I'm checking in during a busy time of year, when there won't be a lot of choice as to room (or in my case, cabin) locations. I didn't even make a room request for this trip, because I know inventory will be limited.
I'm not so sure if I will do online check in for my stay in August or not. I'm staying at BLT on opening day, and I do have some specific room requests. I'm torn between just having the requests on the reservation and doing the online check in, or having the requests on the reservation and just showing up extra early that day to do check-in in person so I can discuss the requests. I don't know if everyone else does online check in, and I don't, if that's going to reduce the available rooms I can choose from if I go in person. So I am very interested to hear how many people receive their requests.
