Robertjack it’s an owner for me that you have replied me. Yes I must share my tour experience to visit Grand Palace. The palace is located in a busy location and therefore, it is reachable by multiple means. Grand Palace is huge and there are lots of rooms inside which would take some time for exploration. This is a must see when visiting Bangkok. The Grand Palace is quite grand and worth it despite the crowds.
I also visited Lumphini Park, Thon Buri and Bangkok Art and Culture Centre except Grand Palace over there.
