This summer 2026, you're probably planning an awesome trip. But trust me, there are some summer travel traps that everyone falls into. I've wasted money, spent hours queuing, and felt like I was in a comedy movie. To help you avoid that, I've compiled common mistakes and how to dodge them.
Quick Facts
- Ideal time: June-August, but avoid the last week of July (peak Western travel season)
- Suggested days: 3-5 days for one destination, 7-10 days for combined tours
- Reference budget: 3-5 million VND/day (includes accommodation, transport, entrance fees)
- Getting around: Hop-on hop-off buses or rent a motorbike (if you're confident)
- Connectivity: Use an eSIM from SimNha to avoid losing signal when you need Google Maps or ride-hailing – I use the 5GB/7-day plan for only 99k, super stable
Mistake #1: Booking flights too early… or too late
Many think the earlier you book, the cheaper it is, but that's not always true. Airlines often release cheap tickets 3-4 months ahead, but if you book right when they go on sale, prices might be higher because promotional seats are gone. Conversely, booking last-minute leads to sky-high prices.
Quick tips:
- Track prices on Google Flights for 2 weeks, book when prices drop sharply.
- Avoid booking on weekends – prices are often 10-15% higher.
- For long-haul flights, try booking a round-trip ticket instead of two one-ways.
💡 Tip: Book on Tuesday or Wednesday – many airlines release mid-week deals.
Mistake #2: Choosing a hotel based only on low price
I once booked a homestay for 200k/night thinking “cheap is fine,” but when I arrived, the room was moldy, had no AC, and was 10km from the center. I thought I was saving money, but ended up wasting time and transport costs.
Smart accommodation checklist:
- Location: Near the train station or main bus terminal.
- Reviews: Read at least 10 recent reviews, prioritize those with real photos.
- Amenities: Air conditioning, fridge, strong WiFi (if you need to work).
- Cancellation policy: Choose free cancellation within 24-48 hours.
⚠️ Note: Don't fully trust pretty booking photos – check Google Maps for real user images.
Mistake #3: Not buying travel insurance
Travel insurance may seem like a waste of money, but just one illness or lost luggage incident will prove its worth. A friend of mine once lost her suitcase at the airport without insurance – zero compensation.
Types of insurance you should have:
- Travel medical insurance: Covers hospital bills if you get sick (about 200-500k for 7 days).
- Baggage insurance: Compensation for lost or damaged items.
- Trip cancellation insurance: Refund if you have to cancel for an emergency.
| Insurance type | Reference cost (7 days) | Main benefit |
|---|---|---|
| Medical | 200k-500k | Hospital fees, medication |
| Baggage | 100k-300k | Lost/damaged luggage |
| Cancellation | 150k-400k | Refund for tickets, hotels |
Mistake #4: Packing too much
“Just in case” is the mantra that doubles your suitcase weight. In reality, you only wear 30% of the clothes you bring. I once packed 5 pairs of shoes for a 3-day trip – ended up lugging a heavy suitcase and not using 3 of them.
Smart packing tips:
- 3-2-1 rule: 3 tops, 2 bottoms, 1 pair of shoes (for 3-4 days).
- Bring quick-dry fabrics: Like polyester, nylon.
- Shoes: One pair of sneakers for walking, one pair of sandals (if going to the beach).
- Vacuum compression bags: Reduce clothing volume by 50%.
📌 Note: If traveling to Europe in summer, bring a light jacket as evenings can be cool.
Mistake #5: Not checking documents and visa requirements
I once almost missed a flight because my passport was about to expire (less than 6 months). Many countries require a passport valid for at least 6 months from the date of entry. Same for visas – don't assume “visa-free means done,” because some visa-free countries still require an electronic registration.
Document checklist:
- Passport: Valid >6 months, with blank pages.
- Visa: Check validity and type (tourist, business, etc.).
- Insurance: Print a hard copy or save PDF.
- Round-trip flight ticket: Some countries require it.
- Vehicle documents (if renting): International driver's license if needed.
⚠️ Note: Take photos of all documents and store them on your phone and email in case you lose the originals.
Mistake #6: No backup plan for connectivity
Running out of data roaming while in the middle of nowhere is a nightmare. I once got lost in Bangkok because I ran out of 4G and had to run into a 7-Eleven to buy a new SIM. Since then, I switched to eSIM – convenient and cheap.
Comparison of connectivity options:
| Type | Cost (7 days) | Advantages | Disadvantages |
|---|---|---|---|
| International roaming | 200k-500k/day | No need to change SIM | Very expensive |
| Local physical SIM | 100k-300k | Cheap | Must find and install SIM |
| eSIM (SimNha) | 99k-299k | Buy online, activate instantly | Requires eSIM-compatible phone |
💡 Tip: Download offline Google Maps and a translation app (Google Translate) in case you lose signal.
Final words
Summer travel is meant to be fun, but sometimes small mistakes can ruin the whole trip. I hope these hard-earned lessons help you avoid trouble and enjoy a perfect vacation. And don't forget, a SimNha eSIM will keep you easily online – I've tried it and found it great, especially when you need to check maps or book a ride.
