OP I would tread very carefully..
Is your horse being taken care of?
You already said you love the BO and the boarders.. just the busy-ness sucks. Is there a time where you can go do things on your own? It must be exhausting having a bunch of people around you doing their thing but look at your options before you consider moving.
Barns proclaim things to get you to move to them instead... and when you get there it may not be all it is cracked up to be, or worse.. they neglect your horse.
Keep in mind that moving a horse is also stressful.
Really think about it. If your horse is happy and cared for, then you just need to survive summer OR find someplace quiet to ride.
I used to be at a barn with over 200 boarded horses.. that's a lot of people in 3 arenas, 1 XC course, and the state trails. But I budgeted my time and found some peace and quiet. I am sure you can too, if that's the only thing that ails you in this scenario.
