I just faced the same dilemma with to assemble a 4 tier wedding cake (this past Friday) on site or at my kitchen – I opted to assemble on site because with all the gananche and fondant, everything weighed a ton and it was to scary to transport assembled. All tiers had the supports in them already so when I arrived I just placed each on top of the other ( I used the SPS system). As an emergency kit, I bring everything I would need to redecorate the cake – in my case, luster dust because two tiers were painted silver so i could fix any smudges, extra dragess and sugar crystals – in case any fell off, extra fondant and my extruder (to cover up the gaps between the tiers – I didn’t use ribbbon). You should bring extra gumpaste flowers in case any break or if you somehow damage the fondant – you can cover it with a flower, :-). Better to bring more than you think you’ll need because you never know what might go wrong and this way you can be prepared for anything. Leave yourself about 90 minutes to assemble and repair or finish decorating onsite – better safe than sorry if you finish early. Good luck and I hope everything goes well.
