How important is the video feed quality? If performance is sketchy, the first thing to go is the video quality. You have a decent chance of maintain the voice, and chat should be no problem. But it kind of depends on how the online classroom is set up. Is it in a browser, with a streaming feed separate from the chat box? or is it an all-in one application? The all-in-one is more risky in that it may decide to halt if it is getting poor performance. Standard browser streaming will just continue on a best effort unless it breaks down really bad.
As far as Wi-Fi strength.... it varies from room to room, floor to floor. Public areas tend to be well covered. Request a pool view, and you may find the signal stronger on your balcony. Or put on headphones and sit by the pool!
