Planned industrial action in August will see more than 40,000 workers walk out, leaving four out of five train services cancelled.
Train staff have already walked out for multiple days in June and July.
The strikes on August 18 and 20, organised by the RMT Union, will see staff members walk out in protest over wages, working conditions and job security.
Sadly this clashes with Airbourne, which is planned for August 18-21. Due to the nature of strikes, August 19 and 21 are likely to be disrupted too.
A spokesperson for Visit Eastbourne said: “We are monitoring the situation regarding the planned rail strike action on August 18 and 20 and have put preliminary plans in place.
"We are awaiting further announcements to confirm that the rail strike will definitely be going ahead on these dates, once this confirmation has been received full plans will be communicated.”
