There are plenty of other museums included in the Museum Month discounts, including the famous Birch Aquarium at Scripps, the Maratime Museum, the Automotive Museum, and more. Make sure to check out the full list, and to pick up your Museum Month pass when you stay at a Hilton.
Getting the most from your Hilton stay
If you stay at Hilton hotels even somewhat-often, you may want to open a Hilton credit card.
Hilton offers three different personal American Express credit cards — the "regular" Hilton Honors American Express Card, the Hilton Honors American Express Ascend Card, and the Hilton Honors Aspire Card from American Express.
The Aspire comes with the most benefits, but also has the highest annual fee, so it's best for those who are fairly loyal to Hilton. However, if you plan to apply for the card and stay for a weekend in San Diego, and maybe another weekend within the year, the card's annual fee will pay for itself.
1. Hilton Honors American Express Card
Welcome offer: 75,000 Hilton Honors points when you spend $1,000 in the first three months.
The baseline Hilton Honors credit card is a stellar option for those who occasionally stay in Hiltons and have use for the welcome offer or benefits, but aren't true brand loyalists or road warriors.
It offers complimentary Hilton Honors Silver elite status, which includes benefits like late check-out, free water bottles during stays, a free 5th night on reward nights, and more points earned during stays. When you spend $20,000 on the card in a calendar year, you'll get upgraded to Gold status, which includes the same perks as silver, plus free breakfast and room upgrades.
Silver status will apply to your Museum Month stay (and any other stay), so you'll get your benefits right away.
The card earns 7x points per dollar spent on Hilton purchases, 5x points per dollar spent at restaurants, gas stations, and supermarkets within the US, and 3x point on everything else.
Travel website The Points Guy subjectively values Hilton Honors points at 0.6¢ each — that makes the bonus worth $450.

2. Hilton Honors American Express Ascend Card
Welcome offer: 125,000 Hilton Honors points when you spend $2,000 in the first three months.
Instead of Silver status, like the no-fee card, the Ascend offers complimentary Gold status. That comes with the same benefits as silver, plus two major additions: you'll get free breakfast during your stay, and you'll be eligible for a room upgrade, assuming there's a free room available.
The Ascend earns 12x points on Hilton purchases, 6x points at restaurants, gas stations, and supermarkets — all within the US — and 3x points on everything else.
Between the 125,000-point welcome bonus, and the fact that the Ascend card offers a free weekend night when you spend $15,000 on it within a calendar year, you've got the makings of a nice long hotel stay without having to pay a thing.
The card also comes with 10 free day passes to Priority Pass airport lounges, and offers a free weekend night when you spend $15,000 on it within a calendar year. The Ascend has a $95 annual fee, but chances are the benefits will offset that for you.

3. Hilton Honors American Express Aspire Card
Welcome offer: 150,000 Hilton Honors points when you spend $4,000 in the first three months.
The premium Hilton Honors American Express Aspire card has a hefty $450 annual fee, but it comes with so many perks, benefits, and rebates that it's more than worth paying for Hilton loyalists.
First, it offers up to $250 in Hilton resort statement credits each card membership year, as well as a up to $250 in airline fee credits per calendar year. Right away, those two credits cover more than the annual fee.
But wait, there's more. The Aspire also offers a $100 Hilton on-property credit every time you book a stay of two nights or longer at a Hilton property — you just need to book through a specific website for cardholders. You can use this right away during a San Diego month stay.
The card also offers a free weekend night reward each year — regardless of how much you spend — and a second weekend night if you spend $60,000 on the card in a calendar year. It also comes with complimentary top-tier Diamond status which, as you'd expect, entitles you to greater benefits than other levels of status.
The Aspire earns a tremendous 14x points per dollar spent with Hilton, 7x points on flights booked with the airline, car rentals, and at US restaurants, and 3x points on everything else.
