For those who cannot make the journey in a day, they have to make arrangements for accommodation and leave only after they have been able to register.

This is unpredictable since people will be traveling from all communities across the constituency to register not forgetting that people who do not possess the Ghana card will have to arrange and possibly travel with two guarantors to help them register.
The above also implies that eligible registrants will have to abandon school, work, and other economic activities for the days that they will be trying to register.
It will also come at a great cost to eligible constituents since they have to bear the cost of transportation, accommodation amidst heavy rain falls, and frequent accidents on the lake.
I believe that the EC by its current decision is denying persons who otherwise are eligible to register the opportunity to do so.
