VFT basic question

Hello all

I have a very basic question. Here in montreal we have a very hot week ahead. Like 30C the day, but my appartment remain at 29C at night.

I have to close the room's door because of my 3 cats. So my vfts will have no temp drop at night for a week or 2.

Its allright or i will have problems ?
