Just a quick subjunctive question

[LearningSpanish]

Quizás sea mejor si __________ a Tonga en el invierno, el clima allá es muy agradable.

It might be better if they went to Tonga in the winter, the climate there is very nice.

Could someone please help me with what follows si here - should I use the subjunctive 'fueran'? because they're not actually going it's just my subjective viewpoint that they should go.

Thanks in advance for any suggestions or explanations.

"Fueran" is fine if they're not going on holidays. If they are, then "van" would sound a little better.

Quizás sea mejor si van a Tonga ...
Quizás sea mejor que vayan a Tonga ...
Quizás sería mejor si van(0)/fueran(1) a Tonga ...
Quizás sería mejor que fueran(1)/vayan(2) a Tonga ...

(0) forma más asertiva.
(1) coordinación automática "de libro" para todos los casos; no aporta información temporal (cuando ocurriría la acción) ni fija la intención de la frase
(2) coordinación más común, también aceptada; dice que el viaje se realizará en un futuro

(1) y (2) tienen diferentes tiempos del hablante, pero en ambas éste se muestra más vacilante que en el caso (0)

Awesome, thanks guys

so ... just to see if I have it straight in my head

Quizás sea mejor si fueran ... It might be better if they were to go ... (it's a suggestion and they may well not go in fact their going might not be at all on the cards)

Quizás sea mejor si van ... It might be / Perhaps it's better if they go ... (we're sure it would be better) and does this one sound like we think there's a good possiblity that they will?

Quizás sea mejor que vayan ... It might be better that they go (and does this one sound like they probably are (hmmm or they definitely are?) but we don't really know if it'll be better)

I think you got it right.
Your last two options sound pretty close in meaning to me, but context would make it clear enough.
