hey hey J&T
you're welcome for all these answers posted. the forum always willing to give you good bad and ugly. don't know what cities you are on with tour, i'm sure you will have some free time along they way.
after doing some research of course come back to ask so you will be prepared, people, places and things to see & do. seen too many travelers not prepared or searching and were unhappy. they may give you option and then you decide what excites you after what the tour does.
pack light, it will be HOT in august, some people have found a laundermat in town (washer/dryer, carry small coins, we took small container of detergent, dryer sheet) near cafe, had lunch/drink & people watched and soon it was done. crowds during daytime with daytrippers, evenings they have gone and enjoy roaming the streets/markets, never know if things happening in the towns. your guide will inform you when you ask.
my first trip was years ago to rome 6 nights, then a 17 day transatlantic cruise to florida. i was determined to ride the "fast train" anywhere, friend says no time, i'm a big girl with big girl pantaloons & will go by myself!! she agreed and we went to naples, one of best day trips even though gritty, garbage everywhere, italian cops/guards with uzis, guns, armoured tanks. was a riot and we laughed so much, stopped for cocktails by bay and train back. i'm from big island hawaii in a small plantation town on hamakua coast with 4,000 people, talk about something totally different for me. have been back a few times to other big cities and different countries, you are gonna get the bug and wanna travel again. LOL
