- When you confirm a reservation and final payment is received by Sonic Tours for a scheduled group series at least 60 days prior to departure, Sonic Tours will purchase coverage for your vacation travel through Travel Guard, a third party insurance carrier, at no additional charge to you (see details of coverage in our brochure or "Travel Insurance") page at this website. Exceptions: city packages, online specials or any other promotions. We also offer an optional protection plan at your own expense, when we receive your final payment inside of 60 days prior to departure.
