What rooms do they have for four people?

You should check out directly with the hotel. This venue is for general information.

Yes they can accommodate 4 adults in two queen size beds or adjoining rooms or add a cot. The Lotte is top notch, no worries. I've stayed and highly recommend

The reservation desk should be able to clarify. We stayed in a room with 2 double beds which would work for 2 adults with 2 kids. May be tight sleeping 4 adults in that setup...

Call the front desk to check availability.
