Your friends are arriving at 2;30, PRIME TIME, and will take them awhile to get through immigration, so you could be looking at 4 hours. For an 8 year old, that's eternity.....lol Take a taxi to Doctor's Cave beach ( drag your luggage with you, no big deal, I am sure a lot of folks to something of the same ) . Relax , and your son will love spending time on that beach. You can also get food and drink while you are there.
