Hello, friend!
I'm sorry I couldn't see your question in a timely manner because the description of the question triggered sensitive words.
This depends on the actual environment of the hotel. However, according to your description, 100 users use Internet access and video services. The mainline access is 100 Mbit/s, and 4 to 6 Mbit/s bandwidth is sufficient for each router on each floor.
The above suggestions are for reference only.
Thanks!
