I only have Klook links on that article page and theirs are vetted and checked. That company we haven’t actually used for about 3 years – we used a different one last time. I will be sure to remove their name with this further information- I don’t think they are still in operation…
What I will say is that this website you have linked has incorrect information regarding the border crossing, as since before this was published you must get out of private cars to go through immigration. Therefore have deleted the link so that I don’t have to delete your comment – with thanks

Thank you for your prompt response! So your link goes to SGMYtaxi.com, according to this article this service is considered one of the “illegal” ones.
Are you certain that the rules haven’t changed, as it apparently happened last year – I am bit worried and need to be sure before I book everything!

No not at all. Normal taxis can’t do it, but special taxis and cars can. Just follow the Klook link in this article.

This is your digital arrival card – it replaces the old physical one.

Hi, sorry it makes perfect sense – the link had changed so I’ve updated it and the current ones give you 48hrs to return and you buy your water park pass in addition (we use Klook and my affiliate links are in the article too). I’ve updated a few little bits and pieces too. We went last year as well, and we’ve done 4 LEGOLANDS now and this one has the best fun water park and is the cheapest for everything too! (By far). Absolutely let me know if you have any further issues or questions, and do join my Facebook groups for both Legoland Malaysia and Singapore Universal – I will put the links at the end of the article!

But also, I think you mentioned you did 1-way via bus only — is there a separate link for that? Or have I missed it.

I hope this made sense, thank you in advance!

Not a stupid question at all! We checked in at the hotel because we stayed there the night (We are heading back next week and will do the same thing!)
