2 adults/2 teens who have never visited Thailand before and have zero knowledge of the country, but want to explore the sites and feel like we're on vacation. We're likely looking for an all inclusive type of experience for the first visit. Subsequent ones would be different. What city would you recommend for a first timer? We'd be visiting for about a week, maybe a day or two more. We're the Hilton/Marriott types...not the Four Seasons, so I'm guessing upper 3* or 4*'s? Some place where my younger teens would feel comfortable grabbing some late night ice cream at 8pm without us escorting them.
