As much as I liked Bangkok Pattaya for its vibrance, a rich religious backstory and the unending shopping escapades, I felt that unless you are looking for loads of shopping or lots of good non-vegetarian street food and some gogo shows and bars, this ain't your place to be. Ofcourse it does have its culture and the magnificent temples of the likes of reclining buddha and the much adored Vat Arun, however the main attraction does remain its voyeuristic nightlife.
Would I come back to Bangkok Pattaya again? Not until I've explored most parts of the world for sure. would I come back to Thailand? Yes most likely to go visit Phuket and shop along the way maybe.
Coming to the good chunk of it if you are looking for a trip with friends where you can enjoy the blue-water beaches, do lots of shopping, eat some great non-veg food and have a decently good night-life all without burning a hole in your pocket then Bangkok-Pattaya it is. Definitely a one time try.
They say Pattaya is a more notorious version of Goa and Bangkok is more upmarket and clean version of Mumbai which is true but only till a certain extent. Bangkok has alot of personality to offer it can make you all contemplating while you are at one of the Wats at the same time it can make you child-like greedy when you are out to shop, it can make you test your wits with the scorpions etc offered to eat at the same time it can sweep you off your feet away with one of the friendliest night life it offers. The gogo shows can be depressing for some and exciting for some but what Bangkok does is offer you alot of emotions al different from one another.
Pattaya on the other hand has distinct 2 features which one can exhaust completely the colourful life at Walking Street and the Beautiful Blue Beaches around Pattaya which will make you want to extend your trip. Indulge in adrenaline rushing water sports or just take a colourful tube and float around the clean blue sea, you will be left asking for more definitely.
Bangkok has alot to offer for everyone and the amazingly cheap ticket rates just make it a perfect quick excursion for students who would end up spending around the same for any trip in India. A 17k return ticket and even cheaper stays available makes Bangkok and Pattaya a first option for most first time abroad travellers.
