Expedia Rate plans are based on two pricing models: Per-day pricing or Occupancy-based pricing.
Per Day Pricing
This is an industry standard strategy that you’re most likely already familiar with. You may know it is a ‘daily/nightly rate’ – it’s a simple flat fee per rental unit with a specified maximum number of occupants.
If the base number of occupants for your rental property is 4, bookings will cost the same for a party of 1 compared to a party of 4.
With this pricing model, you can't add an extra guest fee.

Occupancy Based Pricing
Here’s where things get interesting on Expedia. As you may have guessed, the OBP strategy focuses on cost per guest instead of cost per rental unit.
A typical OBP strategy may look like this:
1 Guest – $100
2 Guests – $150
3 Guests – $200
If you set a rate for 2 guests, but not for one, a single guest will be charged the rate for 2 guests. That’s your base price.
Just like the PDP strategy, if the maximum specified occupants is exceeded, each extra will be charged a fee per night.
With this pricing model, you can use an extra guest fee.
