Las Palmas in November

[Arclight]

After crossing from Newport, RI last summer, we are currently in northern Portugal awaiting a weather window to depart for Gran Canaria and then on to the eastern Caribbean. I had hoped to depart earlier, but conditions have not permitted it. Our plan is to sail to Las Palmas as soon as our port opens. I am, however, concerned that the ARC Rally will make it difficult for us to find a slip, mooring or anchorage. Will this be the case? If so, any recommendations for an alternate staging port would be most welcomed. TIA
