Hi @Lukelhm
The timeline only work when signed into your Google account in Google Maps. Could it be that you by accident used another Google Account while traveling or could you have turned off location history?
Another explanation could be that the spam filter caught your contributions, but that would le not affect your timeline data.
I can confirm from your public profile that you have added 376 reviews and only 354 of them are public.
I do see some photos from Aruba in your public contribution list. Please use Incognito mode to check.
You can use the form called Account Investigation for contributions not visible on Google Maps if you believe that some of your contributions have been wrongfully unpublished. Keep in mind, it takes several weeks for the check to be done, and you will not be notified about the result, so I suggest you check the status of your reviews once a week or so.
Best of luck
