I have just returned from 3 nights on gili air and thought id share my boating experience.
i was travelling alone (male)with a 2&1/2 yr old and a 4&1/2 yr old and had organised a private speed boat thru my hotel in senggigi it cost $90 (just for the boat)for the 3 of us for a 9 min journey,
on the return they were meant to pick us up at 9am and hadnt showed by 9 30 so we walked to the public boat harbour and caught the local boat at 11am for $1 for the 3 of us, a local helped carry my son on and at the other end we shared a cart $3 out to the taxi rank.
it was a great experience not too mention alot cheaper and we never felt unsafe.
i hope this helps others make a decision on how to get to the islands
