A city label is not a compact route
A Tema outing can focus on a market visit, a meal or the coast. Decide which matters most before adding stops. Places sharing a city name aren't necessarily convenient to combine within your available time.
Use the actual addresses and your starting point to compare routes. Include where you need to end the day, especially if different people are travelling home in different directions.
Give the market a purpose
If Community One Market is your main stop, choose what you want to browse or buy. Allow space to carry purchases and avoid scheduling another long walk afterwards by default.
If the coast is the priority, choose a specific venue or access point instead. A broad shore pin doesn't establish toilets, seating or food.
Make the optional stop truly optional
Tell the group which part may be dropped if the day runs late. Otherwise every suggestion can become a promise. A good meal near the main stop may be a better finish than another transfer.
Compare Tema Community One Market with your chosen coastal destination, then commit to one as the anchor. Check visitor access separately for any port-related idea; a harbour is a working facility, not an unrestricted sightseeing area.
