Another location that the Grim Cheaper and I stopped by a couple of weeks ago while doing some stalking in the South Bay was the Manhattan Beach Marriott, which stood in for the supposed-Beverly-Hills-area hotel where the West Beverly High Senior Prom was held in the Season 3 episode of fave show 90210 titled “The Prom Before the Storm”. I found this location thanks to fellow stalker Geoff, from the 90210Locations website, who was kind enough to put together an entire 90210-themed South Bay stalking list for me as soon as he found out that I was heading down that way. Sadly, due to some major traffic that the GC and I encountered on our way down there (darn you, 405!), we were not able to spend as much time in the area as I had hoped and only managed to hit up a couple of locations, one of which was the prom hotel. Ironically enough, not only had the GC and I actually stayed at the Manhattan Beach Marriott a few years back, but thanks to its appearance in an early episode of The O.C., I had even blogged about it. So the fact that I did not recognize it when it appeared in “The Prom Before the Storm” episode is highly embarrassing! I mean, what kind of a stalker am I???

Only the exterior of the Manhattan Beach Marriott Hotel was featured in the episode, in the scene in which Liam Court (aka cutie Matt Lanter – sigh!), Annie Wilson (aka Shenae Grimes), Naomi Clark (aka AnnaLynne McCord) and the rest of the West Beverly High gang arrive at their Senior Prom. As you can see in the screen capture located on the bottom right above, producers put up curtains to block the interior of the hotel in the scene as it did not match up with the interior set that they had created at Manhattan Beach Studios where the series is lensed.
That set, which was centered around Silver’s (aka Jessica Stroup’s) half-baked Cirque du Soleil prom theme, is pictured above.
I am very happy to report that the hotel looks exactly the same in person as it did in the episode. Ironically enough, the Manhattan Beach Marriott is eerily similar in appearance to the Universal Sheraton, where Brenda Walsh (aka Shannen Doherty), Dylan McKay (aka Luke Perry), Donna Martin (aka Tori Spelling) and the rest of the original West Bev gang attended the spring dance in the Season 1 episode of Beverly Hills, 90210 aptly titled “Spring Dance”.
The exterior staircase located just east of the hotel’s front entrance also made an appearance in the episode as the spot where Ivy Sullivan (aka Gillian Zinser) caught her then-boyfriend, now-husband Raj Kher (aka Manish Dayal) drinking.
As I mentioned above, the Manhattan Beach Marriott Hotel was also featured in the Season 1 episode of The O.C. titled “The Debut”. In the episode, the interior of the hotel masqueraded as the interior of Newport Beach’s Pelican Hill Country Club where the dance rehearsals for Marissa Cooper (aka Mischa Barton) and Summer Roberts’s (aka Rachel Bilson’s) Debutante Ball were held.
Both the hotel’s Grand Lobby, which as you can see above has changed its color scheme drastically since the episode was filmed;
and the Manhattan Ballroom, which was unfortunately closed when we showed up to stalk the place but which you can see photographs of here, were featured in the episode.
Big THANK YOU to fellow stalker Geoff, from the 90210Locations website, for finding this location!
Until next time, Happy Stalking!
