There are lots of people who live in Pattaya part-time or year-round who 'never get involved with nightlife there'. That includes my spouse and myself, and most of the people we know who also live here. The location is terrific to start--we can be at our center city Bangkok getaway condo in less than 2 hours--with a drive on the Motorway that's much easier and faster than, say Hua Hin. Suvarnabumi is only about 1.5 hours away--very convenient as we like to travel.
Spouse and I have been car-shopping and just about every auto brand imaginable is available in Pattaya, including 3 or 4 of the new Chinese brands. We ended up buying an suv from BYD, which has a dealership in town. No need to drive long distances to get to a dealership. Ditto that for a selection of good hospitals, and good dental and eye care.
Shopping is excellent, with both Terminal 21 and Central Festival Mall, as well as some other shopping centers. Movies in English at several different movie complexes. Good big box stores, including Index, Home Pro, Boonthavorn, and others. Also good supermarkets with Makro, and several branches of Big C, Lotus, Villa Market, etc. Plus numerous local food markets.
Lots of recreation available with golf courses, badminton and tennis courts, public gyms, snorkeling, biking trails, other boating activities, etc. We love to eat out and Pattaya has tons of restaurants--and you don't need to go to the tourist areas to find them. We are on the Darkside and there are lots of good restaurants on this side of Sukhumvit.
By far the biggest draw has to be both the variety of neighborhoods to choose from and the equally large variety of housing available, at all price points, whether one chooses to rent or own. There's likely a neighborhood--with a good choice of housing--to fit just about any lifestyle. Whether you want a big pool villa in a quiet area or an oceanfront condo on one of the beaches--or something more modest--you'll be able to find it in Pattaya.
