DAY_PACKAGE:

DID Description    UID  VID1   Spa Day         1   191   Spa Day         2   201   Spa Day         9   172   Adventure Time  4   162   Adventure Time  6   163   Family Fun Day  3   183   Family Fun Day  4   173   Family Fun Day  7   183   Family Fun Day  10  194   Relaxation Date 5   20UID: User IDDID: Day Package IDVID: Voucher ID

Given the above tables, find the day packages with highest participant count where all participants are related to one another as either 'family' or 'club members'.

The query should return:

DID Description Participant_Count1   Spa Day         32   Adventure Time  2  

Please assist me any kind soul, thank you! I have been stuck at this for hours. T-T

I only know how to return total participant count:

SELECT Description, COUNT(DISTINCT UID) AS Participants_CountFROM DAY_PACKAGEGROUP BY DescriptionORDER BY Participants_Count DESC
