My wife, 8 year old son and I will be flying to Riga on July 10th. We land at 3 p.m. and plan to be in Latvia 10th, 11th, 12th and depart for Estonia on the 13th. We plan to visit Gutman's cave and Cesis old town on the 13th on the way to Viljandi (Estonia).
1) Are we missing any "must see" sights?
2) Should we book hotels for each night in different towns or stay in Riga itself? (All 3 of us love to travel and drive around, so we're open)
PS: We love scenic locations, landmarks and a little bit of the "not so touristy stuff".
Thanks for your help.
