Let's~
Verb(+object) + ([ด้วย]) + [กันนะ/เถอะ]
[ด้วย] = together
[กันนะ/เถอะ] = already mean [Let's do(something)together], therefore [ด้วย] is often omitted.
1.[Let's go to the airport(together).]
ไปสนามบิน(ด้วย)กันนะ
2.[Let's go eat(together).]
ไปกินข้าว(ด้วย)กันเถอะ
Better to~
Verb(+object) + [ดีกว่า]
*The verb version of[comparative forms of adjectives]....[ดีกว่า] is always followed by a hidden action that is being compared in the sentence.
It would be vetter to go eat (than to stay home).
ไปกินข้าวดีกว่า(อยู่บ้าน)
