The deadline has been set to 5 December for indicative numbers to be supplied to the hosts and with the cost likely to be at least £2,000 it is a big decision to make.
Steve Jacobs, chairman of the Island Games Association of Jersey, has so far received confirmation of around 120 participants.
He said: ‘The big teams are still to confirm such as basketball, volleyball, athletics and football so we are looking at a team of 160 plus.’
