Just returned from a weekend at sea resort. Don't remember it being so busy at this time of year despite worse than average weather. Vacations with a bit of social distancing do work. We have now single digits daily positive cases in Lithuania so rules are no more than 5 people together, sanitizers everywhere and masks while in shops, public transport and ordering food and drinks at the bar or takeway (but not while sitting at a table), most inside activities still closed. Restaurant tables outside are very busy but almost completely empty inside.
So I think when travel will open soon to similar places abroad people will travel to get warmer weather and sea. But we do not expect to have flights allowed to failed places like UK or Russia anytime soon. And travel by own car might still be preferred.
