Less can end up costing you money though - some of the event packages (Rose & Crown fireworks) and Signature Restaurants have charged either no show or the full price for a no show person in the group. This happened to us (had booked 3 for R&C fireworks dinner and only had 2 go - we paid the full event package charge for our missing person - I tried to call in advance, but that didn't work); somewhere on this forum I read about a person's experience at a Signature restaurant. For us going forward, we will always get our reservation modified in advance (or cancel it) to be on the safe side... or, invite a solo traveler to join us and spread a bit of Disney magic!
