Large group traveling Ghana - Togo?

1: if you are 50 students I would rent a bus, unless you are going to split up into smaller groups and travel to different places. You will go nowhere with this many people trying to use the infrastructure already in place.

2: Border crossings are not too much of an issue if you have your visa before hand and all of your documentation. The crossing will get backed up and be very slow with your large group. Maybe call a couple of days before hand and explain your situation and see what is recommended, or if extra staff could be on hand to take care of it. But be prepared for being asked for a handout either way, if you have your stuff in order saying no should not effect things.

3: Depending on the places you are going there are not going to be a whole lot of places that can accommodate 50 people even without prior bookings.

4: Yes it is safe, just work with some common sense, and be aware with your large group it would not be hard to target if someone did choose too.

I would recommend splitting up into smaller groups or a hiring a destination management firm.

Your going to have a great time. Crossing over is easy. I would agree to rent a bus. we used a company Called VIP out of Accra for a band we drove up to Tamale from Accra. I think they charged around 3-4000 Cedi. That's going up to the far north. You might want to look into hiring someone to assist you in your Journeys. Also, Check to make sure they are not stamping your visa for 30 days upon returning. You might have to cough up some money for a little extension for 60. Do the same at the Airport when you arrive. I think they are stamping 60 days when arriving at the airport now. Sometimes 90.

It's going to be almost impossible to get accommodations in the same hotel for that many people. Professional tour companies don't even take on this many people in one group. Logistically, it's going to be a nightmare. Better to split into many small groups. Most of the hotels I stayed at would not have been able to accommodate even ten people because most of them aren't that big to begin with and there are always going to be guests already checked in before your group arrives.

You're also going to have problems finding restaurants with a group of 50. These are less developed countries, and in many places there is inadequate electricity so the food is prepared from scratch. Even a group of 20 descending upon a small restaurant at once in a poor country, you'd be in for a very long wait.

If you split into many small groups, it'll be much easier to get around and everyone will have a better time.

No 3 is right. Don't try it! Ghana could not cope. You could probably hire a bus, but the rest would be horrific, The boarder crossing would take hours, and I would think the only place you could stay would be vacation student accommodation.
If none of you have been to Ghana before, and your post seems to suggest that, I would have thought it worthwhile to send someone in advance. Ghana is an easy place to visit, but with 50?
