Armenia & Georgia Solo Travel

Hi all, I'm a solo traveller from the UK heading to Armenia and Georgia from june 8th-20th and would appreciate some advice from people who've visited.

My planned split:
Yerevan: 4 days
Tbilisi: 4 days
Kutaisi: 3 days

Budget is £30/40 per day (not including hostels & transport).

Primarily will be focused on history (especially USSR related), architecture, beer, football & rugby (looking to watch World Cup when I’m there too). Would like enough time to see the cities, a day trip or two and have a few nights out. I've read that the allocated time I’ve given to each place is sufficient but may not appropriately cover day trips.

Based on my interests and budget is the time allocation sufficient and possible?
