Which of these four courses would you pick for a corporate day with a meeting space and a relaxed round, and why?

All four are solid choices for a Thailand corporate day. Thai Country Club (Chachoengsao) offers prestige and tournament-grade facilities perfect for formal events. Alpine Golf and Sports Club (Bangkok) combines a challenging championship layout with dining and meeting spaces, ideal if you want a seamless day from tee to post-game. Black Mountain Golf Club (Hua Hin) provides a fantastic clubhouse and strong networking spaces in a resort setting. Siam Country Club - Plantation Course (Pattaya) gives a scenic environment with meeting facilities to host corporate guests. For most Bangkok-based groups, Alpine is the most convenient option.
