When staying at a hotel while working at an assignment, I try to stay at a Marriott hotel. Their Residence Inn chains have a kitchen which I like to have. I like Marriott because they have a large footprint especially since they bought the Starwood preferred group chain (think Sheraton). So whether I am traveling domestically or abroad, I can typically find a Marriott hotel to book. Since I am a Titanium member (their highest elite status), I can request late checkout up to 4pm. This is convenient if I have a late flight or want to store my things before moving into my apartment.
When traveling for leisure I love to stay at Hilton hotels. Since I am a Diamond member (their highest elite status), they often treat me as royalty. Think room upgrades, free breakfast for my guests and me, and lounge access. I especially love staying at Hilton hotels abroad because they are usually very luxurious. When I went to Bali in 2019, they upgraded me (for free) to a huge suite. Instead of just a standard bedroom, I had a dining room and living room too. They also gave me free breakfast at their expansive buffet, and allowed my 3 guests to dine with me for free as well.
Since I stay at Hilton and Marriott chains frequently, I definitely have a credit card of each brand. This allows me to accumulate points to stay there for free. If you are interested in getting either of these cards, check out my referral links below.
