Tengo una reserva.
When to use
You will typically say this immediately after greeting the front desk staff, often while handing over your passport or ID card.
How it works
The phrase relies on the first-person present tense of the verb 'tener' (to have). In Spanish, subject pronouns like 'yo' (I) are usually dropped because the verb ending already indicates who is speaking.
- Tengo: I have
- una reserva: a reservation
Register
This is broadly neutral and perfectly polite for all service interactions. It does not require formal address markers.
