Hi,, I have the exact same problem...
Initially, I booked a good location. It was a standalone building, 2 stories, both indoor and outdoor included, enough to fit about 500-600 pax, although I only have 150 -180 pax planned.
Catering included, Sounds System included, Wait staff included.
I went for all the food tasting...! Which was perfect. All my plans were in shape.
But about a year before the wedding date, they start to ignore my emails and calls. For quite a long time.
Then, about 10 months before my wedding, they finally tell me that their lease ends around June next year, which means they cannot hold my wedding.
Now I am in a fix. HELP MEEEE!!!
