I haven't stayed at the Capitain's Inn but as an apartment owner in El Gouna I do know it. It's right in the Marina which is full of excellent restaurants. I have met people on the dive boat who have stayed there and been very happy. All the dive centres will pick you up every day. There are shuttle buses every 15 minutes to Downtown El Gouna or you can walk by following the red brick path. Every Friday there is a party in the Marina. You are also right next to Mangroovy beach which is beautiful.
