For this, I actually like staying in the con hotel, because it's really easy to go back to your room, maybe have room service, and go flomp. Although it's out at Heathrow, which is a bit more annoying, because airport hotels are deeply soulless. However, it's not like most people will be making a racket in the corridors outside your room.
Eastercon is also quite friendly to introverts, and people who have to nope out of interaction because you're out of interaction points.
