We’re usually a party of 2. There are some restaurants I’ve had to book for 4 every trip for years, Ex. Tutto Italia. Even booking the first day I could, the only times that would show up for a party of 2 would be something like 2:30 or 8 pm. But if I booked for 4 I could get anytime I wanted. So I’ve booked for 4 a few times each trip, then just changed to 2 when we checked in. I usually use the website & was never able to get the option to modify down to 2 that other posters talked about. The last trip, I used the app to modify & did get the option to drop our party down to 2 at our already booked time. I’ve never had a problem with checking in for less than the booked number of guests, even at a prepaid meal like CRT. The bill was recalculated after the meal & the overpayment was refunded with no issue what so ever.
