Exod 14:6-9 (KJV)
6 And he made ready his chariot, and took his people with him:
7 And he took six hundred chosen chariots, and all the chariots of Egypt, and captains over every one of them.
8 And the LORD hardened the heart of Pharaoh king of Egypt, and he pursued after the children of Israel: and the children of Israel went out with a high hand.
9 But the Egyptians pursued after them, all the horses [and] chariots of Pharaoh, and his horsemen, and his army, and overtook them encamping by the sea, beside Pi-hahiroth, before Baal-zephon.
As far as I can tell, when the Israelites saw the Egyptian army, this was the first time (of a long subsequent series) that they complained since leaving Egypt.
Exod 14:10-12 (KJV)
10 And when Pharaoh drew nigh, the children of Israel lifted up their eyes, and, behold, the Egyptians marched after them; and they were sore afraid: and the children of Israel cried out unto the LORD.
11 And they said unto Moses, Because [there were] no graves in Egypt, hast thou taken us away to die in the wilderness? wherefore hast thou dealt thus with us, to carry us forth out of Egypt?
They were being a bit sarcastic in verse 14:11 about no graves in Egypt. The Egyptians were world famous for their tombs and graves.
Exod 14:11 (ABP)
11 And they said to Moses, Because there were no [existing tombs] in Egypt you led us to be put to death in the wilderness? What is this you did to us bringing us forth from out of Egypt?
Exod 14:11 (Aramaic Bible in Plain English)
And they said to Moshe, “Because there are no tombs in Egypt have you led us that we should die in the wilderness? Why have you done so to us and have brought us out from Egypt?
Logically speaking, they had the right to complain. They would be no match against chariots and they had nowhere to escape to. But, God told Moses to divide the sea so they could go through it.
Exod 14:21-22 (KJV)
21 And Moses stretched out his hand over the sea; and the LORD caused the sea to go [back] by a strong east wind all that night, and made the sea dry [land], and the waters were divided.
22 And the children of Israel went into the midst of the sea upon the dry [ground]: and the waters [were] a wall unto them on their right hand, and on their left.
Conveniently, the sea bed going across the Gulf of Aqaba at Nuweiba is at one of the highest points along the entire gulf and less steep than other points.
The crossing at Nuweiba would pretty much have to a miraculous event. And I think for this reason it is not considered an option for many scholars. But, according to the text, it would be the most plausible location for the Red Sea crossing to me.
