Travel light, pack the essentials and a spare or two but leave the massive heavy suitcase at home as you rarely need or use all the stuff you packed just in case .. and if you do next extra it’s easy to rinse stuff out and dry overnight or just treat...
Biggest barrier to a summer get away is simply making the decision to go .. it’s too easy to prevaricate.. even looking at travel sites makes it worse .. too many decisions .. just picking a destination and booking makes it happen!
