In Hyatt and Marriott family hotels in the USA. I haven't had problems using zoom to host meetings from my laptop, although my elite status tends to automatically give me the faster internet if a hotel offers it.

If you don't use a virtual background, think about where you want to position yourself for the meeting. IMO it's unprofessional to see a bed in the background, and you might not want it to be obvious that you're in a hotel room (sign on the back of the door, those random cardboard signs that have largely vanished due to COVID-19, view out the window, etc.).
