Best spots to propose
Choose a waterfront setting or a quieter indoor spot depending on the tone you want. Potomac Plaza is the obvious outdoor pick for river views and a fountain/reflecting pool backdrop; the Grand Ballroom Terrace adjoins the MGM Grand Ballroom and faces the Potomac as well.
If you prefer a private dining or intimate setting, several restaurants and private/semi-private dining rooms can host small proposals or rehearsal dinners. For a dramatic indoor moment, consider asking at the bright atrium-style lobby or in a private suite before stepping out for photos.
- Potomac Plaza — waterfront terrace with fountain and reflecting pool (outdoor option).
- Grand Ballroom Terrace — ~6,000 sq ft outdoor terrace adjoining MGM Grand Ballroom with Potomac views.
- Private dining — ask event staff about semi-private rooms for 12–40 guests within select restaurants.

|---|---|---|
| Potomac Plaza | Waterfront proposals & larger groups | Outdoor; has fountain/reflecting pool; catering must be in-house |
