We had a free shuttle and free access to Siam Park during our week's holiday. Amazing place to visit. Spotlessly clean and tidy. Plenty of rides & slides for all ages. Food is reasonably priced. Plenty of sunbeds around the park. Wave machine is activated every hour at 20 mins to the hour.. stays on for 20 mins. My sons (aged 11 & 9) LOVED it! Plenty of lifeguards on duty. Lockers & changing rooms available but if you don't take valuables you should be fine without a locker. Well worth a visit.
