✕Common Mistakes
Fue una experiencia que no voy olvidar.
The infinitive must be preceded by the preposition "a" after "voy" in the periphrastic future construction.
Fue una experiencia que no voy a olvidaré.
Do not mix the periphrastic future with the simple future; choose one form.
Estuvo una experiencia que no voy a olvidar.
If you want to use "estar" instead of "ser", it changes the nuance and sounds less natural for describing the nature of an event.

Cultural Tip
In Spanish, "olvidar" is used for forgetting facts, events, or feelings, while "recordar" means to remember or to bring something to mind. When you want to stress that something will stay in your memory, the periphrastic future "no voy a olvidar" sounds natural and slightly more informal than the simple future "no olvidaré". Also, "fue" (ser) is preferred over "estuvo" (estar) because you are describing the nature of the experience, not its temporary state.
