There is enough choice for every price range in the "fun" city of Pattaya.
But there can be qualitative worlds between two hotels with the same price.
It is enough mold in the bathroom .. a noisy main street that does not let you sleep .. or the photos of the rooms that have nothing to do with reality. I have been to the following hotels several times myself. Always at least 1 week each. Sutus Court is by far the most popular because the location is really perfect. The March Hotel is the most cozy, you have to walk 10 minutes or take a scooter taxi (30-100 baht). I like to use the "Sleep with me", but only if the price is currently not higher than 25 €. This fluctuates a lot.
Basically, the well-known booking portals such as Expedia, Agoda or booking.com are recommended. The offer is huge, the prices low and the comparison very clear. But every booking portal tries to stand out from the competition and wants you to access and pay as soon as possible. Various tricks are used to hide the fact that you could actually book on another website because the vast majority of hotels can be booked anywhere.
Koh Samui is always a good tip for a period of up to 10 days. Quite a few prefer to stay forever. The island is located near the islands of KoTao and KoPhangan. Island hopping is ideal here. There is a good selection of hotels. From hostel to luxury. Tip: It is very quiet here in the off-season.
