What should I do?
1. Stay in a luxury apartment complex with a jolly Thai buddhist.
2. Ride 60km to Petchburi, stay there and see some nice caves.
3. Get the train with Alan to Bangkok.
Things to consider:
I need to get to Battambang and then back to Bangkok by the 9th of April.
I'm still alive 
Go for the experience that gives the most joy or will learn the most or where you will have the most fun, and most of all you gain insights about yourself and how you interact with the world. There are many caves in the world so how special are these? If historical and spiritual perhaps yes?
Why is a buddhist living in luxury? Doesn’t that go against the whole buddhism thing?
It’s his sister’s place but there are heaps of rich buddhists anyway right?
I vote caves. Always Nature. Also Petchburi sounds like a funny version of my name. Otherwise Buddhist Luxury
