These caves are smaller, but less touristic and more natural. Instead of having meal on board, dining in cave will give you a romantic meal in sparkling candle light, which could be your most memorable experience when visiting Halong Bay.
A special diner like that usually requires an extra fee, so why it’s worth to pay? Below are some reasons for its costly price:
- Being a romantic night with a rose petal path which leads to hundreds of candles light up the cave
 - Being a dreamy private meal with your love partner or a relaxing time in cozy area with your family or friends
 - Being an extraordinary buffet party carefully arranged by cruise’s chef and staff
 
Actually, overnight cruise trip in Halong Bay itself is appealing enough, and extra fee around 150 USD/person for this activity should be well considered. However, these are some special occasions which you might be willing to spend money for:
- You want surprise your fiancée with an uncanned proposal
 - You are in honeymoon
 - You want to have an awesome wedding ceremony
 - You wish to have an exceptional birthday party
 - You hope to hold a distinctive gala diner for your team or company
