YEs, I believe weather sealing is important.  Not important enough for me to move from the small Fuji camera to the larger ones.  I am currently using an X100F. It it always with me.  Rain or shine.  Yes, if it is raining I keep it under my coat as I would with a WR camera.  

I refuse to to give my camera to the power to have me stop taking pictures.  

This was taken 1.5 years ago with my X70.  It was raining a bit....

Once I had to stay 1.5 months in Kolkata, India, where the humidity was off the charts, worse than what I have seen even in Florida. I remember my glasses turning completely white from the condensation every time I was leaving the hotel. The air itself was soaked in water.
 
First of all, changing lenses in this environment would be suicidal for modern camera. But even if the lens stays put on, you need WR, and you still need to put your camera in a plastic bag when you leave air conditioned room.
 
And even after these precautions I would not be surprised if something would corrode after prolonged use in your camera.

These are the "recommended" list of focal length for a typical wedding. FL in full frame equivalence
 
24mm
35mm
24-70mm
85mm
70-200mm
 
In your case, I would do this,
 
18-55mm (shoot wide open)
35F2 (shoot wide open)
Use a on or off camera flash set to bounce 45deg forward. Put an orange gel and set your camera WB to tungsten. (That's provided that you'd be shooting in mainly incadescent indoor lighting). Try to get a good balance of flash exposure and back ground lighting. I would avoid too stark a diference, i.e. background too dark.
With your lens, expose for highlights and let your camera's excellent high iso performance do it's work. ISO3200 is very comfortable with the T2.
 
If you have to rent, I would recommend the 23F1.4 or F2 and the 56F1.2 or 90F2. Otherwise, your existing lenses are actually quite workable.
 
Get a good combination of these shots.
Pre-wedding preparation shots, individual groom and bride. Intimate and mood shots with a tele will give privacy and intimacy. Capture static items like shoes, rings, corsages, gown, etc....please arrange them properly and tastefully beforehand. Lots of smiles and happiness with friends, bridemaids, etc...
Shots of anticipation. Groom waiting at isle, hall, room etc.
Bride Arrival shots. Father/guardian giving away bride, etc
A tele for close-ups of mood shots like emotional moments, tears, smiles, etc...
A wide for overall capture of the environment, mood. grandeur, etc
Know the process beforehand, prepare for throwing of bouquet, or any other traditional/cultural practices...
Semi wide angle of reception/party after wedding. Well balanced Flashes works well with environmental lighting. Capture motion of people dancing, smiling, hugs, etc...
Again, a tele for snooping on unsuspecting hugs, smiles, kisses, etc...
 
Hope these helps. All the best.

B&H reimbursed 100% cost of my grey market LG phone, two months short of a full year. I assume that they would do the same for a camera.
 
The question is if Fuji would be willing to service the camera after a year, on a paid basis.
 
For instance, Nikon used to refuse any service for grey market gear in the past, although they changed their policies for D750 recently.
 
I did not have a chance to hear how Fuji handles that.

Have you tried holding it the other way up? 

Hardly surprising, especially the first shot where, probably, even a midrange smartphone camera could have done the job.
 
The question is, of course, how often one gets to use the camera in those ideal circumstances.
