"I never thought I would go there but it indeed was a memorable experience. I did not get the time to venture out but the stay was very comfortable and the hospitality was great," Pallikal, who did well to reach the quarterfinals, told PTI after her return yesterday night.
"An amazing experience here in Riyadh. Top class hospitality and event! Thank you @zalturki and @rbalsaud for all your efforts in making this happen!" she tweeted.
