Narrative:

We were given taxi route B left on U right on circuit breaker cross 13L right on C. It was poor visibility and I was looking outside not at taxi chart. First officer (first officer) and (relief officer) fb had charts up. Fb said circuit breaker to C was more than 90 degree turn. I took this as just helping me find it. Fb was trying to tell me he thought it might be too tight. Taxi chart does not show an island in the middle of that intersection. I thought we had plenty of room since ground sent us that way. With the island in that intersection it made it an uncomfortable turn. Although we made the turn without incident; it would have been better if I had just stopped even if it had caused a big problem for ground control. The aircraft behind us refused the clearance when they saw us make the turn.[suggestion] do not use that taxi route. I will emphasize to first officer's that if they are at all uncomfortable with anything on the ground to just tell me to stop; then tell me what they see.
