These two places are mentioned in every tourist’s Thailand guide-book as must-do Bangkok activities. And for good reason. I was ambivalent about going at first. I’m not really a big fan of Bangkok and herding myself in with a bunch of clueless white people didn’t sound like my cup of tea. Once we arrived to Wat Pra Kaew, I was in full tourist spirit, snapping pictures every few feet.
You can do both in one day, but I would suggest getting out earlier in the morning before the crowds. Both places are held in very high esteem by Thais as national monuments and it’s important to dress and act appropriately in both areas. That includes free modesty skirts and shoulder covers (after you put down a deposit), especially in the Grand Palace.
