There is a lot of information and opinion here, but I will tell you what has been my actual experience. I always do online check-in to make sure my credit card, pin, etc. are set.
Yes, I will choose a request from there, but I know it is not guaranteed. The requests are so basic now, sometimes I don’t even pick one If it doesn’t matter to me.
We are early arrival people, well before I would expect my room to be ready. Even though I have done online check in, I ALWAYS go right to the front desk, and let them know what my requests are, they already know what room I’m in, even though they can’t tell me. If I have already received the text, and I am unhappy with whatever it is, I never go to the room, I just go to the front desk and see if there is something else available. Anytime I have done this, at least six or seven times, I have always been given a different room. I understand rooms are assigned well in advance, but people at the front desk absolutely have the capability to switch things up and give a different option-it might not be exactly what you want, but the power is there.
I do feel like I would have faith in your
travel agent if she made those requests and they are noted on your reservation. There’s no way of knowing until you get there. As others have said, just go right to the front desk, and not your room to see if your requests have been met.
If you all have separate reservations, I would definitely check in online as it will save so much time during the check-in process.
