Thanks for the responses so far folks, a couple of possibilities for later in the year have come up & I will be progressing them if there are no earlier couriers. I have spoken with Business Mail to try & get free passage from Miami for charity donations - they wanted to know which planet I came from to as for FREE things on airflights these days!!
If anyone thinks they might be able to bring them AS LONG AS THERE ARE NO WEIGHT RESTRICTIONS imposed by the flight &/or Tour Company, feel free to let me know who you are travelling with & I will write to them asking for 'special treatment' as these items are for a Charity. Who knows, ONE of them might be compassionate!!
I have written to the person who has acquired them asking for dimensions & weight - I'll put them here (& reply to the PM's) when I have that data. 12 - 15 lbs for THE LOT seems a reasonable guesstimate! That is US $30/35 by Business Mail!
