As per our conversation about period for implement Sun, I would like to change period for implement from 17 Aug- 4 September to 17 – 28 August and keep mam day 5 days because for now I have one system from sale to interface transaction (Concept System) and plan to implement Micros next year and Opera in 2017. However, I already arrange room at Lapa Hotel for Khun Pornpimon period 17-28 August and Khun Pafun period 17-18 August 2015, confirmation letter from hotel as attached. The last one is please ask Khun Pornpimon to call me to appoint with travel from Bangkok to Hua Hin.
