Use gaps in the crowd to cross the dance floor. Keep drinks upright and bags close to your body. A group conversation takes more space than it seems to, especially when other people are moving around you. Take a longer conversation to the edge of the room and keep doors and walkways clear.
Someone dancing nearby may simply prefer that spot. Ask before touching them or joining their dance, and give them space to answer. Step back if they hesitate, turn away or seem uncomfortable. A smile can open a conversation; each person still chooses how the interaction develops.
If you bump into someone or spill a drink, acknowledge it and give them room. A short apology usually handles an accident better than an argument in the crowd. For repeated unwanted contact, move away and speak to a member of staff. Let a declined invitation end there. Continuing to ask, or bringing friends into the interaction, puts pressure on the person who has already answered.
