Unfortunately, it's common for resorts to charge daily fees that can cover a myriad of things (usually basic items) such as internet, health club, water in room, etc. Each property comes up with their own list of items included in the fee, so it's impossible to know what is included w/o asking the individual property... and it can change as they modify it from time to time.
This practice is very frustrating but has become commonplace in the industry... just another way to increase the room rate.
Since your daughter is staying at the hotel now... just ask her to have the front desk explain what's included.
