Do you get free Wi-Fi if you're in the lobby? I'm going to a convention and won't be checking in but I may need to use my laptop while there. Will there be Wi-Fi?

Yes. There is Wi-Fi. I believe you can connect from lobby

I don't think they give it without a reservation. If you belong to Sheraton's rewards program they might.

If you go to the check in desk and let them know you are with a convention, I believe they will give you WiFi access.

No, not without a reservation

No.

I have been in the same situation and have just asked and explained the reason why. In each circumstance they have been accommodating. Just don't be surprised if they say no.

Nope.

No. You need a room to be able to get wi-fi
