Loire to the South of France late June - AC situtation

Your best bet is to contact the hotels on the tour. They should be in your portal by now. Or soon. The same tours don't necessarily stay in the same hotels.

Sorry, I wasn't clear. This is for next year. We haven't yet made the call. This year, we'll be in South of Italy tour in September.

My tour was 2019 so hotels and amenities may have changed, but the only hotel we stayed at with AC was the one in Nice.

Just got back from this tour, which started in late April. There were a few hotels without A/C - either they didn't have it or hadn't turned it on yet for the season. At one of the hotels, there was a nice stand fan (with a quiet mode!) that worked well. In the other's, an open window worked for us. The guide warned the group of at least one place without A/C but said fans were available from the front desk.

Thanks for your replies. I'll keep that in mind.
