We are planning our first trans-Atlantic leaving the Chesapeake (USA) in early May, 2023 for the Mediterranean.  We need to leave the boat in mid-July for about six week somewhere in the vicinity of Valencia / Barcelona, Spain or possibly the Balearics.  We are looking for any recommendations on a marina to leave the boat (44 foot catamaran).  We have contacted a few marinas but none of them are taking reservations this early.  Should we be worried?  How difficult is it to secure a long term mooring in that area in July?  Any and all advice appreciated.
