First Serve Sports Club — not in Pattaya
Location correction
First Serve's own site gives its address as 25/477 Chaeng Wattana–Pak Kret 24, Si Chai Thong 19, Bang Talat, Pak Kret, Nonthaburi 11120. The current Maps listing confirms that Nonthaburi location and active operation. It is therefore not a Pattaya-area venue.
The operator publishes 08:00–21:00 hours Monday through Friday and 07:00–21:00 on weekends, plus +66 2 101 3889 and +66 86 885 8799 as contacts. The record is retained only to document the location mismatch and prevent it being rediscovered as a Pattaya candidate.
Do not include this venue in Pattaya swimming recommendations or area comparisons.
