I wouldn’t take any tripods; filters; speedlites or other “stuff”, apart from the P&S camera as mentioned in the OP.
But the OP mentioned or implied: weight: lack of street shooting experience; convenience of one lens; unsureness of needing telephoto lens; concern of theft or damage (“5DMkIII + Big Fat Red-striped Lens = Steal me”) so what I would use I don’t think would be suitable/useful for Kay.

However I disagree here on one point. Let me explain -
Comparisons and Contrasts of the lens cache available and an explanation of why in Post #7 ONLY the 50/1.4 was recommended as a secondary and “fast” lens:
If an additional faster aperture lens is being considered for use in low light situations, then it's important to directly compare and contrast the functionality and uses of that additional lens, to the functionality and uses of the main working lens.
Let’s assume that we do accept the quality of the Tamron 18 to 270 and it is to be taken on the holiday as the main working lens.
Now let's compare and contrast the value of our choice of an additional “fast” lens - the two lenses which we can choose between are: EF 16 to 35 F/2.8L and EF50 F/1.4 (possibly the EF85 F/1.8, but we'll exclude that for the moment, the rationale should be obvious, please read on).
A salient point to note is - the Tamron 18 to 270 has a Maximum Aperture of F/3.5 from FL = 18mm to FL = 30mm. Let’s agree that for the purposes of C&C with the EF 16 to 35/2.8 that the difference between FL = 30mm and FL = 35mm is insignificant.
Accordingly the gain in Aperture Speed if we choose to take the EF 16 to 35 F/2.8L is a mere ⅔Stop, which arguably could be accommodated in almost all situations with a slight increase in ISO.
On the other hand, (although a short telephoto lens when used on the 7D ) the EF 50 F/1.4 sports a maximum aperture which is a significant 2⅔Stops faster than the Tamron 18 to 270 when it is set at FL = 18~30mm and a whopping 3⅓Stops faster than the Tamron 18 to 270 when that lens is set at FL = 50mm.
