Additional Guest fee as way of offering discount

[Jane353]

Hello!

What is the best way to offer a discount to either a family of 4 or 5, or a couple (or single person for that matter)? I have a single family home with two bedrooms. I am trying to offer a stronger discount for the off season but in my experience if I set the limit of guests at 5 and lower my price, I get a group of friends who pool together and end up using more utilities, linens, etc and leaving a big mess and more cleanup. I've tried to add a fee to over 3 guests in order to accommodate for this but so far have seen no action. My property is in Fort Lauderdale and I need to be careful how I word and charge for everything. I would really appreciate some advice from any hosts who have experience with this. Thank you!
