We are both teachers and can only holiday the last two weeks of July or in August. It looks like the weather is better in Koh Samui than Phuket. Is this right? Would we still get to the beach without umbrellas? If not does anyone have any other suggestions? We have two teenage children and have been to Mexico, Cuba and Egypt in recent years and keen to show them a bit more of the world before they step out on their own. Thank you.
